Description

Technical Field

Detailed implementation manners

[0067] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0068] Please refer to Figures 1-13 as shown, the specific embodiments provided by the present invention are as follows:

[0069] The thermal active volatilization device can be widely applied to various devices in the fields related to liquid volatilization and diffusion, meeting the requirements of different scenarios.

[0070] For example, this device can be used for the volatilization and diffusion of insect repellent or mosquito repellent liquids. Through heating and active diffusion methods, it can quickly improve the volatilization efficiency and diffusion range, thereby achieving a more efficient insect repellent or mosquito repellent function. It is suitable for use in scenarios such as families, outdoor activity places, farmlands, and public areas, providing users with a convenient and reliable solution.

[0071] In addition, this device is also applicable to fragrance devices, such as the volatilization and diffusion of essential oils. Through the thermal active diffusion method, this device can quickly release the aroma molecules of essential oils and evenly diffuse them in the indoor space, creating a comfortable and relaxing environmental atmosphere. Whether it is a family living room, bedroom, or commercial spaces such as office places, yoga rooms, hotels, etc., it can effectively meet the high-quality requirements of users for fragrance experiences.

[0072] In addition to this, this device can also be applied to other special scenarios, such as for the volatilization and diffusion of liquid medicines or disinfectants, providing support for medical places, laboratories, or public health environments. In these scenarios, the thermal active volatilization device can achieve stable and efficient liquid volatilization, improving the overall application effect and safety.

[0073] Refer to Figure 1 as shown, the thermal active volatilization device includes a volatilization core rod 1. The volatilization core rod 1 has an overall slender structure, fully considering the requirements for the absorption and diversion of the volatilizing liquid. One end of the volatilization core rod 1 is an open structure, defined as the first opening 101, and the other end is a closed structure for restricting the liquid from flowing out from this end. Along the axial direction of the volatilization core rod 1, an inner cavity 102 with a set length is formed inside it, and the inner cavity 102 penetrates to the first opening 101 and communicates with the external environment.

[0074] The volatile core rod 1 can be inserted into the volatile container 4 filled with volatile liquid. Specifically, one end of the closed structure is inserted into the interior of the volatile container 4 and maintains a certain contact with the bottom of the container or the liquid level or is completely immersed, so as to ensure that the volatile liquid can be sucked into the inner cavity 102 of the core rod. One end of the first opening 101 is usually located outside the volatile container 4 for the insertion of the heating element of the thermal active volatilization device, and under the action of the heating air flow, the diffusion of the volatile liquid is accelerated.

[0075] Under normal circumstances, the volatile core rod 1 is inserted into the volatile container 4 in the vertical direction. Its vertical arrangement not only helps the smooth suction of the liquid, but also effectively avoids problems such as liquid leakage or reduced volatilization efficiency that may be caused by tilting or inversion. The material of the volatile core rod 1 is usually selected as a porous material with good capillary action characteristics and heat resistance to ensure excellent stability and volatilization performance during heating or long-term use.

[0076] Furthermore, the length of the closed end of the volatile core rod 1 and the inner cavity 102 can be optimized according to the viscosity, density of different volatile liquids and the usage scenarios. 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 volatilization response speed.

[0077] Through the above structure, the volatile core rod 1 can effectively improve the volatilization efficiency under the action of the heating element of the thermal active volatilization device while maintaining the stability of liquid supply, providing a reliable and efficient technical solution for various liquid volatilization devices.

[0078] One or more second openings are provided on the side wall surface of the volatile core rod 1. The second opening is a non-through structure and is usually concentrated on the side wall surface of the volatile core rod 1 close to the first opening 101. Specifically, the second opening is in a concave structure, and its purpose is to increase the effective surface area of the side wall surface of the volatile core rod 1, thereby significantly increasing the volatilization area and volatilization efficiency.

[0079] In the form of a concave structure, the second opening enlarges the side wall surface area of the volatile core rod 1. The larger surface area can provide more volatilization contact surfaces, thereby enhancing the volatilization rate of the volatile liquid.

[0080] The second opening can also help the volatile liquid to be more evenly distributed on the surface of the volatile core rod 1, reduce the retention of the liquid on the surface of the volatile core rod 1, and ensure the continuous stability of the volatilization process.

[0081] In addition, the number and position of the second openings can be designed and optimized according to specific requirements. In some applications, multiple small depressions or a large-range depression structure can be designed to be adjusted according to the requirements of different types of volatile liquids, temperature requirements and volatilization efficiency.

[0082] Reference Figure 1 As shown, the thermal active volatilization device includes an electric heating mandrel 2. This thermal active volatilization device integrates power connection and heat energy output functions to meet the high-efficiency heating and diffusion requirements of the volatilizing liquid.

[0083] Specifically, the structure of the electric heating mandrel 2 includes:

[0084] Power supply end 201: It is used to connect the control circuit and the output end of the power supply through a power supply wire. Here, the output end refers to the port that delivers current to the electric heating mandrel, ensuring that the electric heating mandrel 2 can obtain a stable power supply. Among them, the control circuit and the power supply can be arranged inside the battery compartment. The power supply end 201 usually uses a material with good electrical conductivity and is designed with a reliable fixed interface to achieve a safe connection with the external circuit. In addition, the control circuit is used to adjust the power supply parameters (such as voltage, current) to achieve precise control of the electric heating mandrel 2, so as to adjust the heating temperature and time according to requirements.

[0085] Heating end 202: It is the core heating component of the electric heating mandrel 2, and its length is usually less than the length of the inner cavity 102 of the volatilization mandrel 1. Ensure that the heating end 202 can be completely inserted into the inner cavity 102 of the volatilization mandrel 1 and directly transfer heat to the inside of the volatilization mandrel 1 to promote the rapid heating and volatilization of the volatilizing 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.

[0086] In the working state, power is supplied to the electric heating mandrel 2, and the heating end 202 quickly heats up and transfers heat energy to the inner cavity 102 of the volatilization mandrel 1. The inner cavity 102 usually contains a small amount of air and the gas after the volatilization of the volatilizing liquid. During the heating process, the heat energy causes the temperature of the gas in the inner cavity 102 to rise rapidly, and the gas molecules obtain more kinetic energy, thus significantly enhancing their diffusion ability. These high-temperature gases continuously diffuse outward along the axial direction of the inner cavity 102, promoting the efficient volatilization and diffusion of the volatilizing liquid.

[0087] Specifically:

[0088] The inner cavity 102 mainly contains a small amount of air and the gas generated by the volatilization and evaporation of the volatilizing liquid. Under the heating effect, the density of this mixed gas decreases and the molecular movement rate increases, thus having stronger diffusibility.

[0089] Since the heating end 202 is directly located in the inner cavity 102 of the volatilization mandrel 1, the heat it transfers can quickly increase the overall temperature of the gas in the inner cavity 102 and form 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 thermal active diffusion process.

[0090] Compared with the traditional natural evaporation method, the thermal active evaporation of this device can not only effectively overcome the influence of external factors such as environmental temperature, humidity and air flow, but also significantly improve the evaporation efficiency and diffusion range. Through the synergistic effect of continuous heat energy supply and the design of the inner cavity 102, the device can achieve rapid evaporation and uniform diffusion of the liquid in a short time, meeting the needs of various application scenarios, such as insect repellent, fragrance diffusion or air purification.

[0091] In order to adapt to different types of volatile liquids and application scenarios, the control circuit can be designed to support multi-stage heating power adjustment to meet the different heating requirements of high-boiling-point insect repellent liquids or low-boiling-point fragrance liquids. In addition, to ensure safety in use and the service life of the device, the electric heating core rod 2 usually also integrates an overheat protection function or a temperature feedback module to avoid material damage or safety hazards caused by long-term high-temperature operation.

[0092] Compared with the peripheral heating method in the prior art, since the electric heating core rod 2 is completely inserted into the inner cavity 102 of the volatile core rod 1, all the generated heat is used to heat the air between the two, making the air have a higher kinetic energy, which can quickly pass through the wall surface from the inner cavity 102, evaporate the volatile liquid attached to the wall surface, and drive the volatilized gas and the gas after evaporation to quickly diffuse into the external environment, improving the evaporation effect.

[0093] In a specific embodiment, a certain gap is provided between the electric heating core rod 2 and the inner cavity 102 of the volatile core rod 1, and the two do not directly contact. That is, the inner diameter L1 of the inner cavity 102 of the volatile core rod 1 is greater than the outer diameter L2 of the electric heating core rod 2.

[0094] The reason is that if the electric heating core rod 2 is in direct contact with the inner wall of the volatile core rod 1, a solid heat conduction path will be formed. Since the solid heat conduction efficiency is much higher than that of gas heat conduction, this contact may cause the heat energy to be quickly transferred to the overall structure of the volatile 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 utilization efficiency of heat energy, but also increase the external temperature of the volatile core rod 1, thus affecting the overall safety and evaporation performance of the device.

[0095] 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.

[0096] Specifically, by using gas as the heat energy transfer medium, it is ensured that the heat energy at the heating end 202 is mainly concentrated on the air in the inner cavity 102 and the gas after the volatile liquid evaporates, so as to achieve a uniform and efficient heat diffusion effect.

[0097] Prevent heat energy from directly conducting through the solid to the outer wall of the volatile mandrel 1, thereby reducing energy waste and ensuring that the outer wall temperature remains within a safe range.

[0098] Avoid the problem of overheating of the outer wall caused by solid heat conduction, thereby increasing the service life of the device and the safety of users.

[0099] Through this non-contact structure, the thermal active volatilization device can more accurately control the heating process, while maintaining the stability and efficiency of the device operation, providing a better technical solution for liquid volatilization and diffusion.

[0100] Preferably, 0.2mm ≤ L1 - L2 ≤ 3mm. The existence of the gap provides space for heat convection. Within this range, after the electric heating mandrel 2 is heated, the gas in the gap expands due to heat, forming a natural heat convection phenomenon. Heat 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.

[0101] Reference Figure 3 and 4 As shown, it includes a plugging body 3. The plugging body 3 is arranged at the power supply end 201 of the electric heating mandrel 2 and is used to effectively plug the connection part between the electric heating mandrel 2 and the volatile mandrel 1. Specifically, when the electric heating mandrel 2 is inserted into the inner cavity 102 of the volatile mandrel 1, the plugging body 3 seals the channel of the first opening 101 by sealing contact with the first opening 101 of the volatile mandrel 1.

[0102] The plugging body 3 plays a plugging role at the power supply end 201 of the electric heating mandrel 2, preventing the volatile liquid from flowing out through the first opening 101, thereby avoiding liquid leakage or the volatile liquid entering the power supply end 201 of the electric heating mandrel 2. Through the plugging design, it is ensured that the liquid can only volatilize outward within the inner cavity 102 without affecting the electrical part of the electric heating mandrel 2 and the safety of the circuit.

[0103] The plugging body 3 can also effectively ensure the reasonable layout of the heat energy transfer channel between the electric heating mandrel 2 and the volatile mandrel 1. Under the sealing action of the plugging body 3, the inner cavity 102 of the volatile mandrel 1 remains in a sealed state, and the heat energy can act more focused on the gas within the inner cavity 102, avoiding the interference of external air and ensuring the efficiency of the heating process.

[0104] The plugging body 3 can also play a certain protective role, avoiding the influence of external foreign objects on the electric heating mandrel 2 when it is inserted into the volatile mandrel 1 or causing unnecessary damage. The protective layer provided by the plugging body 3 can extend the service life of the device and improve its stability.

[0105] The material and shape of the plugging body 3 can be adjusted according to the requirements of the specific usage environment to ensure sealing performance while having characteristics such as high temperature resistance and corrosion resistance. For example, the plugging body 3 can be made of silicone or other heat-resistant materials to ensure stable operation for a long time during the heating process.

[0106] In a specific embodiment, the plugging body 3 has an approximate conical structure. The design of this structure enables the plugging body 3 to precisely plug the first opening 101 of the volatilization core rod 1 when the electric heating core rod 2 is inserted into the inner cavity 102 of the volatilization core rod 1. Specifically, when the electric heating core rod 2 is inserted into the inner cavity 102 of the volatilization core rod 1, the conical side surface of the plugging body 3 closely adheres to the inner wall of the first opening 101 to form an effective seal.

[0107] The side surface design of the approximate conical structure enables it to adhere to the inner wall of the first opening 101 of the volatilization core rod 1, ensuring the high efficiency of the sealing effect. Through this structure, the plugging body 3 can come into contact with the first opening 101 when inserted, avoiding liquid leakage or gas overflow, and at the same time ensuring that heat does not escape during the heating process, further improving the heat conduction efficiency.

[0108] The conical structure of the plugging body 3 can effectively isolate the inner cavity 102 and the power supply end 201 of the electric heating core rod 2, preventing heat from directly acting on the power supply end 201, thereby maintaining the high efficiency and safety of heating. This helps to optimize the distribution of thermal energy, avoiding local overheating and interference during the liquid volatilization process.

[0109] The conical structure of the plugging body 3 also has a certain guiding function. When the electric heating core rod 2 is inserted into the inner cavity 102 of the volatilization core rod 1, the plugging body 3 can correct the axial offset of the electric heating core rod 2 to ensure a good centering relationship with the volatilization core rod 1. This prevents direct contact between the two.

[0110] Reference Figure 2 As shown, the heat active volatilization device includes a volatilization container 4 that matches the outer diameter of the volatilization core rod 1 for carrying the volatilization liquid. Specifically, when the volatilization core rod 1 is inserted into the opening of the volatilization container 4, it can plug the opening of the volatilization container 4 to ensure the sealing of the volatilization liquid and the overall sealing of the device.

[0111] In addition, the volatilization core rod 1 is suitable for causing a wetting phenomenon to occur to the volatilization object. The wetting phenomenon means that the volatilization core rod 1 can effectively absorb or contact the volatilization liquid to ensure that the volatilization liquid is evenly distributed along the surface of the volatilization core rod 1.

[0112] Reference Figure 2As shown, a seal body 401 is provided at the opening of the volatilization container 4. A seal opening for inserting the volatilization core rod 1 is provided at the center of the seal body 401. The seal opening is in close fit with the outer surface of the volatilization core rod 1 to form a sealed connection, thereby ensuring that the liquid inside the volatilization container 4 does not leak, and the gas and liquid during the volatilization process can stably volatilize outward.

[0113] Specifically, the seal body 401 can be made of rubber material, which has good elasticity and sealing performance. When the volatilization core rod 1 is inserted into the seal opening, the seal body 401 can provide a sealing effect between its surface and the volatilization core rod 1, effectively preventing the leakage of liquid or gas from the opening, thereby ensuring the tightness of the volatilization container 4 and the volatilization core rod 1. The rubber material has good heat resistance and chemical corrosion resistance, and can maintain a stable sealing effect during the heating process, improving the safety and service life of the device.

[0114] Reference Figure 2 As shown, a liquid absorption ring 402 is sleeved at the opening of the volatilization container 4. The liquid absorption ring 402 is usually made of materials with high liquid absorption performance, such as sponge, fiber material or other substances with strong adsorption properties, and can effectively absorb the volatilized liquid and keep it stable in the device.

[0115] The liquid absorption ring 402 is configured to be movably sleeved at the opening of the volatilization container 4 for easy disassembly and replacement.

[0116] Reference Figure 5 As shown, it includes a protective mesh cover 5. The electric heating core rod 2 is arranged inside the protective mesh cover 5. The protective mesh cover 5 is made of metal or heat-resistant materials with high strength, such as stainless steel or ceramic materials, and has good thermal stability and corrosion resistance. Its main function is to protect the electric heating core rod 2 from external physical interference and damage, and enhance the safety of the device.

[0117] The protective mesh cover 5 has good shielding function, can effectively isolate the contact between the electric heating core rod 2 and the outside world, and reduce the risk factors during the operation process. Especially during high-temperature operation, through the protection of the protective mesh cover 5, the risk of electric shock and scald caused by personnel accidentally touching the electric heating core rod 2 is effectively avoided, improving the use safety.

[0118] 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 heat resistance and corrosion resistance should be selected to ensure long-term stable use under different working conditions.

[0119] Reference Figure 6As shown, in a specific embodiment, the protective mesh cover 5 includes a volatilization area 501. The protective mesh cover 5 forms a plurality of mesh holes 5011 in the volatilization area 501, and at least a part of the volatilization core rod 1 is located in the volatilization area 501. Generally speaking, the upper half of the volatilization core rod 1, that is, the part not located inside the volatilization container 4, is located in the volatilization area 501.

[0120] During the working process, the volatile liquid attached to the surface of this part of the volatilization core rod 1 will be driven by heating. Through the action of heat energy, the liquid gradually turns into gas and diffuses to the outside. The mesh holes 5011 help to enhance air circulation and promote the diffusion of the volatile gas, enabling the volatile liquid to quickly contact the outside air and improving the volatilization effect.

[0121] In addition, the existence of the mesh holes 5011 can effectively prevent foreign objects from entering the volatilization area 501, protect the internal components from physical damage, and prevent users from accidentally touching the electric heating core rod 2 or the volatilization core rod 1, ensuring the use safety.

[0122] Reference Figure 7 As shown, in a specific embodiment, the protective mesh cover 5 includes a connection area 502. This connection area 502 is located below the volatilization area 501 and extends in the vertical direction. The purpose of the connection area 502 is to accommodate the volatilization container 4, ensure the stable installation of the volatilization container 4 in the device, and facilitate the operation of the user. Specifically, the volatilization container 4 can be pushed into the space enclosed by the connection area 502 by sliding, and can be stuck after reaching the designated position to prevent it from shifting or falling off during use.

[0123] In this embodiment, one or more clamping blocks 601 are provided on the bottom side wall surface of the volatilization container 4, and clamping grooves 602 are provided at corresponding positions in the connection area 502. During the installation of the volatilization container 4, the user only needs to slide the volatilization container 4 vertically into the connection area 502, and the clamping blocks 601 will cooperate with the clamping grooves 602 and engage. When the volatilization container 4 slides to the designated depth, the engagement of the clamping blocks 601 and the clamping grooves 602 can effectively prevent the volatilization container 4 from continuing to penetrate, thereby ensuring that the volatilization container 4 is accurately installed in the correct position of the connection area 502.

[0124] Specifically, the shape and size of the clamping blocks 601 are designed to precisely match the clamping grooves 602, enabling the volatilization container 4 to easily slide in and be aligned during the installation process. When the volatilization container 4 reaches the installation depth, the clamping blocks 601 are blocked and fixed, not only preventing the volatilization container 4 from moving due to vibration or external force, but also ensuring that its position will not shift. Through this positioning cooperation, it is ensured that the volatilization container 4 is always in the optimal working position with respect to the electric heating core rod 2 and the volatilization core rod 1, thereby improving the overall working efficiency of the device.

[0125] The distance between the bottom of the volatilization container 4 and the bottom end of the connection area 502 is set between 3 mm and 6 mm. This distance setting is based on safety considerations and is designed to prevent children from easily pulling out the volatilization container 4, thus protecting the safety of children. With this design, even if a child operates it by mistake, it is not easy to directly touch the internal liquid of the volatilization container 4, thereby avoiding the risk of accidental contact with the volatile liquid.

[0126] Specifically, setting the distance between 3 mm and 6 mm ensures the fixation of the volatilization container 4 during the installation process. Within this range, it is very difficult for users (especially children) to easily pull out the volatilization container 4 by simple pulling or touching, increasing safety. This design not only optimizes the performance of the device but also provides an additional child protection function, effectively reducing the safety hazards caused by children's misoperations and enhancing the family-friendliness and safety of use of the product.

[0127] Reference Figure 10 As shown, it includes a device housing, and the device housing includes a first main body 701 and a second main body 702. When a force is applied to the first main body 701 or the second main body 702, one of them can slide relative to the other. Specifically, the sliding design between the first main body 701 and the second main body 702 enables the two to move relative to each other according to the action of an external force, thereby realizing the gradual hiding and exposure of the volatilization area 501.

[0128] During the process of the two approaching each other, the volatilization area 501 is gradually hidden. At this time, the control circuit should automatically stop supplying power to the electric heating mandrel 2 to prevent continuous heating when the volatilization area 501 is hidden. This can effectively avoid the electric heating mandrel consuming electrical energy when it does not need to work, ensuring energy efficiency and safety. When the first main body 701 and the second main body 702 are in full contact, the volatilization area 501 is completely hidden inside the device housing, thereby further improving the safety of the device and at the same time preventing the volatile liquid from being exposed to the outside, reducing external pollution or danger.

[0129] On the contrary, when the first main body 701 and the second main body 702 move away from each other, the volatilization area 501 is gradually exposed. After the control circuit (electrically controlled connection sensing device, for example, a magnetic anchor point is set on the first main body 701, a Hall sensor is set on the second main body, and the Hall sensor is signal-connected or electrically controlled to the control circuit) detects this change, it automatically turns on the power supply to the electric heating mandrel 2 to restore the heating function, ensuring the normal operation of the volatilization device and starting the diffusion process of the volatile liquid. At the same time, a lighting lamp can be configured to turn on the lighting when the volatilization area 501 is exposed.

[0130] The sliding mechanism of the device housing can achieve intelligent shielding and release of the volatilization area 501, automatically adjusting the working state of the electric heating mandrel 2. This not only improves the usability of the device but also adds an additional safety protection function, avoiding unnecessary energy waste and ensuring that the device can efficiently volatilize the liquid when needed. At the same time, this design can effectively prevent users from coming into contact with the volatile liquid or heating element unknowingly, avoiding possible scalds or other safety hazards.

[0131] In a specific embodiment, the battery compartment is placed inside one of the main bodies, for example, inside the first main body 701. This design can effectively integrate the power supply and control circuit, simplify the overall structure, and at the same time maintain the compactness and convenience of the device.

[0132] Reference Figure 7 As shown, the connection area 502 between the second main body 702 and the protective mesh cover 5 forms a sliding socket connection. Specifically, a guiding groove 603 is provided in the connection area 502. The function of the guiding groove 603 is to guide the second main body 702 to maintain a stable path during the sliding process, so as to avoid unnecessary deviation or jamming. Correspondingly, a guiding block is provided on the inner wall surface of the second main body 702, and the guiding block cooperates with the guiding groove 603 to ensure that the second main body 702 can smoothly slide along the set trajectory.

[0133] To achieve more precise state control, the guiding groove 603 is set as a zigzag path in the axial direction of the protective mesh cover 5. The design of the zigzag path has an important role: when the guiding block slides along the zigzag path, the change in the path will cause the guiding block to be blocked, indicating that the second main body 702 and the first main body 701 are in the first separated state. In this state, the volatilization area 501 is completely exposed, allowing the volatile liquid to enter the working state.

[0134] When the user rotates the second main body 702 by a certain angle, the guiding 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 disengage it from the connection area 502, facilitating further operation or maintenance of the device.

[0135] In a specific embodiment, a deformable block 604 is also provided in the connection area 502 of the protective mesh cover 5. The purpose of the deformable block 604 is to ensure a smooth transition during the relative sliding of the second main body 702 through a specific deformation mechanism, and to accurately dock at the clamping position, while avoiding the jamming phenomenon caused by excessive clamping force.

[0136] Specifically, the deformation block 604 is disposed in the connection area 502 and is designed to be deformed under extrusion force during the sliding process of the second body 702. When the second body 702 slides along the guiding groove 603, the deformation block 604 will deform inward due to external pressure, thereby allowing the second body 702 to continue sliding and pass through the deformation block 604. At this time, the deformation block 604 is temporarily in a deformed state to create space for the subsequent clamping process.

[0137] When the second body 702 continues to slide and the card slot inside it corresponds to the position of the deformation block 604, the deformation block 604 will restore its original shape after the external force is removed and complete the clamping in the card slot.

[0138] To ensure smoothness and stability during the clamping process, the design of the deformation block 604 ensures that the clamping force will not be too large. This avoids the situation of complete jamming that may be caused by excessive clamping force, that is, prevents the deformation block 604 from being too tightly clamped with the card slot, which may affect subsequent disassembly or operation.

[0139] The connection area 502 is provided with an observation groove, and the second body 702 is provided with an observation window 7021. The purpose is to enable the user to conveniently understand the remaining amount of the volatile liquid in the volatile container 4, so as to effectively master the working state of the device.

[0140] When the second body 702 is in full contact with the first body 701, the positions of the observation groove and the observation window 7021 will accurately correspond. At this time, the observation window 7021 is located on the second body 702 and is aligned with the observation groove, enabling the user to clearly see the situation inside the observation groove through the observation window 7021. In particular, through this design, at least part of the wall surface of the volatile container 4 is exposed within the observation window 7021 and is in a visible state. In this way, the user can understand the remaining amount of the volatile liquid in the volatile container 4 in real time and avoid the situation that the volatile device cannot work properly due to insufficient liquid.

[0141] The position of the observation groove corresponds to the wall surface of the volatile container 4, and can provide a transparent view to the user through the observation window 7021, ensuring that during daily use, the user can easily monitor the remaining amount of the liquid and the volatilization state, so as to judge whether it is necessary to replenish the liquid or perform maintenance.

[0142] This design not only improves the user experience, but also effectively improves the reliability of the device. The user can clearly understand the operating state of the device and take corresponding measures in time to prevent the device from stopping working due to liquid exhaustion. Through the cooperation of the observation groove and the observation window 7021, the maintenance of the device becomes more convenient, and at the same time, the uncertainty in use and the possibility of failure are reduced.

[0143] Reference Figures 10-13As shown, a portable volatilization system is provided. The design of this system aims to incorporate all the technical features in the above embodiments and focuses on optimizing portability to meet the needs of users in outdoor scenarios, such as for mosquito repellent or insect repellent.

[0144] Traditional mosquito repellent or insect repellent devices mostly adopt an external heating structure, that is, an electric heating element is arranged on the outer periphery of the volatilization core rod 1 to heat the volatilization liquid. However, due to the existence of the external heating element, the device needs to be equipped with an additional isolation element to prevent users from directly contacting the heating part. The addition of the isolation element not only complicates the device structure but also significantly increases the overall size of the device, which is not conducive to portability.

[0145] The isolation element usually needs to reserve a certain isolation space to ensure safety and heat dissipation effect. This space further increases the volume of the device and is not suitable for outdoor use scenarios.

[0146] Based on the above problems, this system introduces a thermally active volatilization device with a built-in electric heating core rod 2. The electric heating element is designed as an insertable structure and is directly located in the inner cavity 102 of the volatilization core rod 1, providing a heat source through internal heating. The heat source is placed in the inner cavity 102 of the volatilization core rod 1, eliminating the need for an additional isolation element, significantly reducing the device size, and improving portability. By directly acting on the inner cavity 102 of the volatilization core rod 1 through internal heating, the heating efficiency is higher, and the heat energy loss is significantly reduced. The heat energy drives the gas (including air and the vapor of the volatilization liquid) in the inner cavity 102 to form a rapid diffusion, promoting the conversion and diffusion efficiency of the volatilization liquid.

[0147] The portable volatilization system of the present invention combines the advantages of the thermally active volatilization device, solving the problems of large size, inconvenience in portability, and low efficiency of traditional devices. Its high efficiency, safety, and compact characteristics make the device show excellent practicality and portability in multiple scenarios, providing users with a more efficient and convenient volatilization solution.
