Description

Technical Field

[0001] This utility model relates to the field of household appliances, specifically a mosquito repellent device based on motor heating and a double-headed fan. Background Technology

[0002] In daily life and work, people's needs for fans are becoming increasingly diverse. Traditional single-head fans can only blow air in one direction, limiting the airflow range. To overcome this limitation, dual-head fans have emerged. Dual-head fans have two fan heads that can be flexibly adjusted in angle, allowing them to blow air in different directions simultaneously, effectively expanding the airflow range and bringing coolness to more areas. Whether in a small room or a larger office space, dual-head fans can better meet people's needs for air circulation and a cooling experience.

[0003] Existing dual-head fans mainly provide airflow, which is relatively simple. In summer and other seasons with many mosquitoes, dual-head fans can only achieve airflow to bring a cooling sensation, but cannot repel mosquitoes at the same time. This means that users still need to use other mosquito repellent tools during use, making it difficult to obtain a convenient experience that combines airflow and mosquito repellency, thus affecting the overall user experience.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] The existing dual-head fans mentioned above mainly provide airflow, which is relatively simple. In summer and other seasons with many mosquitoes, users still need to use other mosquito repellent tools, making it difficult to achieve the convenient experience of combining airflow and mosquito repellency, thus affecting the user experience. The technical solution adopted by this utility model to solve this problem is: A mosquito repellent device based on motor heating includes a motor mounting housing and a drive motor disposed within the motor mounting housing. The outer wall of the motor mounting housing is provided with a receiving groove, and the receiving groove is provided with a mosquito repellent bottle containing mosquito repellent liquid. The heat generated by the drive motor when it is working is conducted through the motor mounting housing to the mosquito repellent bottle to heat the mosquito repellent liquid.

[0006] Furthermore, the receiving groove is an upward-facing slot structure, and the mosquito repellent bottle is detachably installed in the receiving groove.

[0007] Furthermore, the mosquito repellent bottle is tightly fitted to the wall of the receiving groove, and the wall of the receiving groove is provided with a hollow part.

[0008] Furthermore, the mosquito repellent bottle is made of a thermally conductive material.

[0009] Furthermore, the drive motor includes a first output shaft and a second output shaft coaxially arranged with the first output shaft. The first output shaft extends outward through one side of the motor mounting housing, and the second output shaft extends outward through the other side of the motor mounting housing. The receiving groove is located in the central region of the top of the motor mounting housing.

[0010] Furthermore, the length of the motor mounting housing in the horizontal direction is 160mm to 200mm.

[0011] Furthermore, the length of the motor mounting housing in the horizontal direction is 180mm.

[0012] Furthermore, the receiving groove is integrally formed with the motor mounting housing.

[0013] Furthermore, the hollowed-out portion includes a plurality of heat-conducting holes, which are spaced apart on the wall of the receiving groove.

[0014] This utility model also provides a dual-head fan, including the mosquito repellent device based on motor heating as described above.

[0015] The beneficial effects of this utility model are as follows: 1. This utility model provides a receiving groove on the outer wall of the motor mounting housing and places a mosquito repellent bottle containing mosquito repellent liquid in the receiving groove. This allows the heat generated when the drive motor is working to be conducted to the mosquito repellent bottle through the motor mounting housing, thereby heating the mosquito repellent liquid and promoting its evaporation. This facilitates the integration of air supply and mosquito repellent functions, eliminating the need for users to configure separate mosquito repellent devices. This improves the multifunctionality and ease of use of the device and effectively solves the problem that existing dual-head fans mainly provide air supply functions, which are relatively simple. In summer and other seasons with many mosquitoes, users still need to use other mosquito repellent tools, making it difficult to obtain the convenient experience of integrating air supply and mosquito repellent, thus affecting the user experience. 2. By setting a receiving groove on the outer wall of the motor mounting housing, the heat naturally generated when the drive motor is working can be conducted through the motor mounting housing to the mosquito repellent bottle in the receiving groove. There is no need to equip a special heating device to achieve the mosquito repellent function and consume energy. While meeting the mosquito repellent needs, it helps to reduce the additional energy consumption, thereby achieving the effect of energy saving.

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

[0017] Figure 1 This is a schematic diagram of the structure of the dual-head fan of this utility model; Figure 2 This is an exploded view of the dual-head fan of this utility model. Detailed Implementation

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1 to 2 The mosquito repellent device based on motor heating shown includes a motor mounting housing 1 and a drive motor 2 disposed in the motor mounting housing 1. The outer side wall of the motor mounting housing 1 is provided with a receiving groove 3. The receiving groove 3 is provided with a mosquito repellent bottle 4 containing mosquito repellent liquid. The heat generated by the drive motor 2 when it is working is conducted to the mosquito repellent bottle 4 through the motor mounting housing 1 to heat the mosquito repellent liquid. This invention features a receiving groove on the outer wall of the motor mounting housing, into which a mosquito repellent bottle containing mosquito repellent liquid is placed. This allows the heat generated by the drive motor during operation to be conducted through the motor mounting housing to the mosquito repellent bottle, thereby heating the mosquito repellent liquid and promoting its evaporation. This integrates airflow and mosquito repellency functions, eliminating the need for users to use separate mosquito repellent devices. This enhances the device's versatility and ease of use, effectively solving the problem that existing dual-head fans primarily provide airflow, resulting in relatively limited functionality. In summer and other seasons with abundant mosquitoes, users still need to rely on other mosquito repellent tools, making it difficult to achieve the convenient experience of integrated airflow and mosquito repellency, thus affecting the user experience.

[0020] Furthermore, by providing a receiving groove 3 on the outer wall of the motor mounting housing 1, the heat naturally generated when the drive motor 2 is working can be conducted through the motor mounting housing 1 to the mosquito repellent bottle 4 in the receiving groove 3. This eliminates the need for an additional heating device to achieve the mosquito repellent function and consume energy, thus meeting the mosquito repellent needs while reducing additional energy consumption and achieving the effect of energy saving.

[0021] Specifically, when the drive motor 2 is working, the windings of the drive motor 2 will generate heat due to electromagnetic losses and mechanical friction. Typically, the outer casing temperature can reach 50°C to 80°C. This heat is conducted through the heat-conducting material of the motor mounting housing 1 to the receiving groove 3 on the outer wall, and further transferred to the bottle wall of the mosquito repellent bottle 4, thereby continuously heating the mosquito repellent liquid inside the mosquito repellent bottle 4, causing its effective ingredients to evaporate and achieve the mosquito repellent function. It should be noted that this mosquito repellent function depends entirely on the heat generated by the drive motor 2. When the drive motor 2 stops working, there is no heat source provided, the mosquito repellent liquid cannot be heated and evaporated, and the mosquito repellent function will stop immediately.

[0022] like Figures 1 to 2 The accommodating groove 3 shown is an upward-facing slot structure, and the mosquito repellent bottle 4 is detachably installed in the accommodating groove 3; Furthermore, the receiving slot 3 adopts an upward-facing slot structure, which allows the mosquito repellent bottle 4 to be inserted vertically or at an angle from above the motor mounting housing 1, thereby achieving quick installation. When users replenish mosquito repellent liquid or replace empty mosquito repellent bottles 4, they do not need to disassemble the fan housing, motor or other functional components. They only need to take out the old mosquito repellent bottle 4 and put in the new mosquito repellent bottle 4 to complete the replacement, which helps to simplify the operation process.

[0023] Furthermore, the mosquito repellent bottle 4 is installed in the container 3 in a detachable manner, which not only makes it easy to replace, but also supports regular cleaning. After long-term use, the mosquito repellent liquid may leave volatile substances or precipitate in the mosquito repellent bottle 4, affecting the subsequent heating evaporation efficiency or even producing an odor. With the detachable design, users can take out the mosquito repellent bottle 4 and rinse it with water or neutral detergent to remove the residue.

[0024] Furthermore, the slot structure provides good positioning and fixing for the mosquito repellent bottle 4, preventing it from shifting, tilting, or even falling off during fan operation due to vibration, head swaying, or accidental contact.

[0025] Optionally, in some embodiments, the slot structure is an elastic snap-on slot, the side wall of the receiving slot 3 is provided with at least one elastic snap, and the outer wall of the mosquito repellent bottle 4 is provided with an annular or dotted groove at the corresponding position. When the mosquito repellent bottle 4 is inserted into the slot, the elastic snap undergoes a slight deformation, rebounds after passing the bottle body and is locked into the groove, thereby achieving positioning and locking. When disassembling, the user only needs to press down slightly or move it to the side to remove the mosquito repellent bottle 4.

[0026] Optionally, in some embodiments, the slot structure is a guide rail type slot, with a guide rail extending axially on the side wall of the receiving slot 3, and a guide slider at the corresponding position on the outer side wall of the mosquito repellent bottle 4. When the mosquito repellent bottle 4 is installed, the guide slider slides along the guide rail, which not only plays a guiding role and facilitates quick installation, but also restricts the circumferential rotation of the mosquito repellent bottle 4 through the cooperation of the guide rail and the slider, which helps to improve the installation stability.

[0027] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the slot structure is a U-shaped slot, the cross-section of the receiving slot 3 is U-shaped or C-shaped, and it is composed of a bottom wall and a side wall, forming a groove open at the top. The cross-section of the mosquito repellent bottle 4 can be circular, square or any shape that matches the U-shaped slot. The user can directly place the mosquito repellent bottle 4 vertically into the slot. The lower part of the bottle is supported by the bottom of the slot, and the sides of the bottle are limited by the slot walls to prevent it from swaying left and right.

[0028] like Figures 1 to 2 The mosquito repellent bottle 4 shown is tightly fitted to the wall of the receiving groove 3, and the wall of the receiving groove 3 is provided with a hollow part. Furthermore, the mosquito repellent bottle 4 is tightly fitted to the wall of the container 3, which allows for good thermal contact between the side wall of the mosquito repellent bottle 4 and the motor mounting housing 1. This helps reduce the thermal resistance caused by air gaps. Since the heat generated when the drive motor 2 is working is mainly conducted to the mosquito repellent bottle 4 through the motor mounting housing 1, the tight fit design facilitates the efficient and uniform transfer of heat from the side wall of the motor mounting housing 1 to the circumferential surface of the mosquito repellent bottle 4, thereby accelerating and stabilizing the heating process of the mosquito repellent liquid, promoting its continuous evaporation, and effectively improving the mosquito repellent effect.

[0029] Furthermore, the close fit design can further improve the installation stability of the mosquito repellent bottle 4 in the receiving groove 3. Combined with the hollow part, it can ensure the structural stability while allowing the mosquito repellent ingredients to work more efficiently, which is conducive to improving the overall practicality of the device.

[0030] Furthermore, by providing a perforated section in the wall of the receiving groove 3, the amount of material used in the motor mounting housing 1 can be significantly reduced without affecting the main heat conduction path, thereby reducing the weight of the device and manufacturing costs.

[0031] Optionally, in some embodiments, the perforated part is a strip-shaped cross-cut perforation. The groove wall of the receiving groove 3 is provided with horizontal and vertical cross-cut strip-shaped perforations to form a grid-like structure. The cross-cut strip structure increases the complexity of air circulation. After the heat from the motor mounting housing 1 is transferred to the groove wall, the air flows along the horizontal and vertical cross-cut strip-shaped perforations to form a crisscrossing airflow. This can more efficiently transfer heat from the groove wall to the mosquito repellent bottle, and can also increase the contact area between the air and the mosquito repellent bottle 4 to a certain extent, accelerate the heat conduction speed, and improve the evaporation efficiency of the mosquito repellent liquid.

[0032] Optionally, in some embodiments, the perforated part is a honeycomb structure, composed of multiple hexagonal perforated structures arranged closely together. The honeycomb structure has a high space utilization rate, which can provide a large number of air circulation channels while ensuring the structural strength of the tank wall. When the heat generated by the drive motor 2 is conducted to the tank wall, the air flows in the numerous hexagonal perforations, forming a dense airflow network, which quickly transfers the heat to the mosquito repellent bottle 4. Moreover, the honeycomb structure helps to distribute the heat evenly, avoids local temperature being too high or too low, and ensures that the mosquito repellent liquid evaporates continuously and stably.

[0033] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the hollow portion is a plurality of circular structures disposed on the wall of the receiving groove 3.

[0034] like Figures 1 to 2 The mosquito repellent bottle 4 shown is made of thermally conductive material; Furthermore, the mosquito repellent bottle 4 is in direct contact with the motor mounting housing 1. The thermal conductivity of the material of the mosquito repellent bottle 4 directly affects the efficiency of heat transfer from the housing to the mosquito repellent liquid. The mosquito repellent bottle 4 made of thermally conductive material can significantly reduce the thermal resistance of the bottle wall, so that the heat generated by the drive motor 2 can be quickly conducted to the inside of the mosquito repellent bottle 4 through the motor mounting housing 1, thereby heating the mosquito repellent liquid and promoting its rapid evaporation.

[0035] Furthermore, the thermally conductive material has good thermal diffusivity, which can quickly and evenly transfer heat from the contact point to the entire bottle, preventing the mosquito repellent from being overheated in local areas and causing high-temperature decomposition or odor change. At the same time, it prevents other areas from evaporating slowly due to insufficient temperature. Even heating helps maintain a stable and continuous release of mosquito repellent ingredients, which is beneficial to improving the reliability and comfort of the mosquito repellent effect.

[0036] Optionally, in some embodiments, the mosquito repellent bottle 4 is made of food-grade stainless steel. Food-grade stainless steel has good thermal conductivity, stable chemical properties, will not release harmful substances within the temperature range in which the fan operates, and is resistant to high temperatures and corrosion. It will not react chemically with the mosquito repellent liquid, and is highly safe.

[0037] Optionally, in some embodiments, the mosquito repellent bottle 4 is made of high borosilicate glass. High borosilicate glass has moderate thermal conductivity, good light transmittance for easy observation of the remaining amount of mosquito repellent liquid, stable and non-toxic material, and will not produce substances harmful to the human body even when heated. In addition, its smooth surface is easy to clean, which can prevent the growth of bacteria due to mosquito repellent liquid residue.

[0038] like Figures 1 to 2 The drive motor 2 shown includes a first output shaft 21 and a second output shaft 22 coaxially arranged with the first output shaft 21. The first output shaft 21 extends outward through one side of the motor mounting housing 1, and the second output shaft 22 extends outward through the other side of the motor mounting housing 1. The receiving groove 3 is located in the central area of ​​the top of the motor mounting housing 1. Furthermore, the first output shaft 21 and the second output shaft 22 of the drive motor 2 are coaxial and extend to both sides of the motor mounting housing 1, which facilitates the installation of fan blades on the first output shaft 21 and the second output shaft 22 to form a dual-head fan structure. This allows the fan to deliver air from both sides simultaneously, expanding the air delivery range and improving the cooling effect. The coaxial arrangement also ensures the concentricity of the two output shafts, reducing vibration and noise.

[0039] Furthermore, the receiving slot 3 is located in the central area of ​​the top of the motor mounting housing 1, which can receive the heat generated by the drive motor 2 to the maximum extent. The drive motor 2 generates a lot of heat during operation, and the central area is where the heat is concentrated. By placing the receiving slot 3 here, the heat generated by the drive motor 2 can be transferred more directly and efficiently to the mosquito repellent bottle 4 inside the receiving slot 3, which is conducive to accelerating the evaporation of the mosquito repellent liquid and helping to improve the mosquito repellent effect.

[0040] Furthermore, when the fan is running, the first output shaft 21 and the second output shaft 22 drive the fan blades on both sides to rotate and generate airflow. Since the receiving groove 3 is located in the center area of ​​the top of the motor mounting housing 1, it is in the middle of the airflow generated by the fan blades on both sides. The mosquito repellent ingredients emitted by the mosquito repellent bottle 4 can be quickly carried by the airflow on both sides. During the flow, these airflows will quickly bring the mosquito repellent ingredients to a wide area around the fan, avoiding the accumulation of mosquito repellent ingredients in a local area and significantly expanding the mosquito repellent range. At the same time, the continuous flow of airflow can also make the mosquito repellent ingredients more evenly distributed in the environment, thereby more effectively playing the role of mosquito repellent and further improving the user experience.

[0041] like Figures 1 to 2 The length of the motor mounting housing 1 shown in the horizontal direction is 160mm to 200mm; Furthermore, the length of the motor mounting housing 1 in the horizontal direction is 160mm to 200mm, so that a reasonable space distance is maintained between the left fan head and the right fan head installed at both ends of the motor mounting housing 1. When the distance between the two fan heads is too close, the two airflows are prone to interfere with each other, resulting in airflow swirling, turbulence or pressure cancellation, which leads to reduced air volume, uneven air delivery, reduced air output efficiency, and easy wind speed fluctuation, affecting the comfort of use.

[0042] Furthermore, by controlling the length of the motor mounting housing 1 to be between 160mm and 200mm, the gap between the two fan heads can be effectively increased, avoiding cross-interference of their airflow in the near field area, so that the two airflows can each form an independent and stable air duct, thereby achieving a more uniform air delivery effect.

[0043] Optionally, in some embodiments, the length of the motor mounting housing 1 in the horizontal direction is 160mm. When the length of the motor mounting housing 1 in the horizontal direction is 160mm, the distance between the fan heads on the left and right sides is at the smaller value within this range. This can avoid mutual interference of airflow caused by the distance being too close, ensure stable air output efficiency, and make the overall structure of the fan more compact.

[0044] Optionally, in some embodiments, the length of the motor mounting housing 1 in the horizontal direction is 200mm. When the length of the motor mounting housing 1 in the horizontal direction is 200mm, the distance between the fan heads on the left and right sides is larger, and the airflow on both sides has more independent diffusion space, which can further reduce the possibility of airflow collision and cancellation, and the stability of the air output efficiency is stronger. The larger distance allows the fan to deliver air over a wider range.

[0045] like Figures 1 to 2 The length of the motor mounting housing 1 shown in the horizontal direction is 180mm; Furthermore, the length of the motor mounting housing 1 in the horizontal direction is 180mm. When the length of the motor mounting housing 1 in the horizontal direction is 180mm, the distance between the fan heads on the left and right sides is moderate, which is in the middle of the range of 160mm to 200mm. This can effectively avoid airflow interference caused by too small a distance, ensure stable air output efficiency, and at the same time prevent the overall size of the fan from becoming too large due to excessive distance.

[0046] Furthermore, the length of the motor mounting housing 1 in the horizontal direction is 180mm, so that the airflow on both sides has sufficient independent diffusion space, which can uniformly deliver airflow to the surrounding area. This not only meets the local air supply needs of a small area, but also takes into account the cooling effect of a larger area, which is conducive to achieving a balance between compactness and air supply range.

[0047] like Figures 1 to 2 The accommodating groove 3 shown is integrally formed with the motor mounting housing 1; Furthermore, the one-piece molding design makes the receiving groove 3 and the motor mounting housing 1 a continuous and complete structure, without any weak links caused by connecting parts. During the operation of the drive motor 2, vibration and impact forces will be generated. The one-piece molding structure can better withstand these forces, reduce the risk of structural damage caused by loose or broken connections, and effectively extend the service life of the device.

[0048] Furthermore, the one-piece molding design simplifies the production process, reduces assembly steps, eliminates the need to manufacture the receiving slot 3 separately before installation, helps reduce labor and material costs in the production process, and also improves production efficiency and ensures the consistency of device quality.

[0049] Furthermore, the one-piece molding design enhances heat conduction. The one-piece structure allows the heat generated by the drive motor 2 to be transferred to the receiving slot 3 more directly and efficiently, reducing heat loss at the connection points and enabling the mosquito repellent bottle 4 to receive heat more quickly, effectively improving the heating and evaporation efficiency of the mosquito repellent liquid.

[0050] like Figures 1 to 2The hollowed-out portion shown includes a plurality of heat-conducting holes 31, which are spaced apart on the wall of the receiving groove 3; Furthermore, the spaced heat conduction holes 31 ensure that the wall of the receiving groove 3 retains sufficient solid parts. These solid parts can serve as the main path for heat conduction, reducing the obstruction to the heat conduction from the motor mounting housing 1 to the mosquito repellent bottle 4, and allowing heat to be transferred to the mosquito repellent bottle 4 more efficiently.

[0051] Furthermore, the spaced heat conduction holes 31 enable more uniform heat conduction, preventing the continuity of heat transfer from being disrupted due to the lack of local wall space caused by the excessive density of the heat conduction holes 31. This ensures that all parts of the mosquito repellent bottle 4 are heated relatively evenly, which is beneficial to improving the stability of mosquito repellent liquid evaporation.

[0052] Furthermore, the spaced heat conduction holes 31 can retain more of the groove wall structure, which helps to enhance the support strength of the accommodating groove 3 for the mosquito repellent bottle 4, prevent the mosquito repellent bottle 4 from being unstable due to insufficient groove wall strength, and at the same time reduce the impact of the heat conduction holes 31 on the overall structural rigidity, effectively extending the service life of the device.

[0053] like Figures 1 to 2 The illustrated dual-head fan includes a mosquito repellent device based on motor heating as described above; Specifically, by installing this mosquito repellent device inside the dual-head fan, it is possible to achieve dual-head airflow and expand the cooling range. At the same time, the heat generated by the drive motor 2 during operation heats the mosquito repellent liquid in the mosquito repellent bottle 4, eliminating the need for additional heating elements. This not only saves energy consumption but also simplifies the device structure. The airflow generated by the dual-head fan can also quickly and evenly diffuse the mosquito repellent ingredients into the surrounding environment, allowing users to enjoy cool airflow while being protected from mosquito bites. This greatly improves the convenience and comfort of use and achieves an efficient combination of airflow and mosquito repellent functions.

[0054] The implementation method of Example 1 is as follows: The mosquito repellent device based on motor heating includes a motor mounting housing 1 and a drive motor 2 disposed in the motor mounting housing 1. The outer wall of the motor mounting housing 1 is provided with a receiving groove 3, and the receiving groove 3 is provided with a mosquito repellent bottle 4 containing mosquito repellent liquid. The heat generated by the drive motor 2 when it is working is conducted to the mosquito repellent bottle 4 through the motor mounting housing 1 to heat the mosquito repellent liquid.

[0055] This invention features a receiving groove on the outer wall of the motor mounting housing, into which a mosquito repellent bottle containing mosquito repellent liquid is placed. This allows the heat generated by the drive motor during operation to be conducted through the motor mounting housing to the mosquito repellent bottle, thereby heating the mosquito repellent liquid and promoting its evaporation. This integrates airflow and mosquito repellency functions, eliminating the need for users to use separate mosquito repellent devices. This enhances the device's versatility and ease of use, effectively solving the problem that existing dual-head fans primarily provide airflow, resulting in relatively limited functionality. In summer and other seasons with abundant mosquitoes, users still need to rely on other mosquito repellent tools, making it difficult to achieve the convenient experience of integrated airflow and mosquito repellency, thus affecting the user experience.

[0056] The implementation method of Example 2 is as follows: Based on Example 1, Example 2 also has the following implementation method: The receiving groove 3 is a slot structure with the opening facing upward, and the mosquito repellent bottle 4 is detachably installed in the receiving groove 3.

[0057] The implementation method of Example 3 is as follows: Based on Example 1, Example 3 also has the following implementation method: the mosquito repellent bottle 4 is tightly fitted to the wall of the receiving groove 3, and the wall of the receiving groove 3 is provided with a hollow part.

[0058] The implementation method of Example 4 is as follows: Based on Example 1, Example 4 also has the following implementation method: the mosquito repellent bottle 4 is made of thermally conductive material.

[0059] The implementation method of Example 5 is as follows: Based on Embodiment 1, Embodiment 5 further includes the following implementation: The drive motor 2 includes a first output shaft 21 and a second output shaft 22 coaxially arranged with the first output shaft 21. The first output shaft 21 extends outward through one side of the motor mounting housing 1, and the second output shaft 22 extends outward through the other side of the motor mounting housing 1. The receiving groove 3 is located in the central area of ​​the top of the motor mounting housing 1.

[0060] The implementation method of Example 6 is as follows: Based on Example 1, Example 6 also has the following implementation method: the length of the motor mounting housing 1 in the horizontal direction is 160mm to 200mm.

[0061] The implementation method of Example 7 is as follows: Based on Example 6, Example 7 also has the following implementation method: the length of the motor mounting housing 1 in the horizontal direction is 180mm.

[0062] The implementation method of Example 8 is as follows: Based on Example 1, Example 8 also has the following implementation method: the receiving groove 3 is integrally formed with the motor mounting housing 1.

[0063] The implementation method of Example 9 is as follows: Based on Example 3, Example 9 also has the following implementation method: the hollow part includes a plurality of heat conduction holes 31, and the plurality of heat conduction holes 31 are spaced apart on the groove wall of the receiving groove 3.

[0064] The implementation of Embodiment 10 is as follows: A dual-head fan includes a mosquito repellent device based on motor heating as described above.

[0065] Specifically, by installing this mosquito repellent device inside the dual-head fan, it is possible to achieve dual-head airflow and expand the cooling range. At the same time, the heat generated by the drive motor 2 during operation heats the mosquito repellent liquid in the mosquito repellent bottle 4, eliminating the need for additional heating elements. This not only saves energy consumption but also simplifies the device structure. The airflow generated by the dual-head fan can also quickly and evenly diffuse the mosquito repellent ingredients into the surrounding environment, allowing users to enjoy cool airflow while being protected from mosquito bites. This greatly improves the convenience and comfort of use and achieves an efficient combination of airflow and mosquito repellent functions.

[0066] The implementation method of Example 11 is as follows: Based on Example 2, Example 11 also has the following implementation method: The slot structure is an elastic buckle type slot, and the side wall of the receiving slot 3 is provided with at least one elastic buckle. The corresponding position of the outer wall of the mosquito repellent bottle 4 is provided with an annular or dot-shaped groove. When the mosquito repellent bottle 4 is inserted into the slot, the elastic buckle undergoes a slight deformation, rebounds after passing the bottle body and is locked into the groove, thereby achieving positioning and locking. When disassembling, the user only needs to press down with a little force or move it to the side to remove the mosquito repellent bottle 4.

[0067] The implementation method of Example Twelve is as follows: The difference between Example 12 and Example 11 is that the slot structure is a guide rail type slot, the side wall of the receiving slot 3 is provided with a guide rail extending along the axial direction, and the corresponding position of the outer side wall of the mosquito repellent bottle 4 is provided with a guide slider. When the mosquito repellent bottle 4 is installed, the guide slider slides along the guide rail, which not only plays a guiding role and facilitates quick installation, but also restricts the circumferential rotation of the mosquito repellent bottle 4 through the cooperation of the guide rail and the slider, which helps to improve the installation stability.

[0068] The implementation method of Example Thirteen is as follows: The difference between Example 13 and Example 11 is that the slot structure is a U-shaped slot, the cross-section of the receiving slot 3 is "U" or "C" shaped, and it is composed of a bottom wall and a side wall, forming a groove with an open top. The cross-section of the mosquito repellent bottle 4 can be circular, square or any shape that matches the U-shaped slot. The user can directly place the mosquito repellent bottle 4 vertically into the slot. The bottom of the bottle is supported by the bottom of the slot, and the sides of the bottle are limited by the slot walls to prevent it from swaying left and right.

[0069] The implementation method of Example Fourteen is as follows: The difference between Example 14 and Example 9 is that the hollow part is a strip-shaped cross-cutting hollow. The groove wall of the receiving groove 3 is provided with horizontal and vertical cross-cutting strips, forming a grid-like structure. The cross-cutting strip structure increases the complexity of air circulation. After the heat from the motor mounting housing 1 is transferred to the groove wall, the air flows along the horizontal and vertical cross-cutting strips, forming a crisscrossing airflow. This can more efficiently transfer heat from the groove wall to the mosquito repellent bottle, and can also increase the contact area between the air and the mosquito repellent bottle 4 to a certain extent, accelerate the heat conduction speed, and improve the evaporation efficiency of the mosquito repellent liquid.

[0070] The implementation method of Example 15 is as follows: The difference between Example 15 and Example 9 is that the hollow part is a honeycomb structure, which is composed of multiple hexagonal hollow structures arranged closely together. The honeycomb structure has a high space utilization rate and can provide a large number of air circulation channels while ensuring the structural strength of the tank wall. When the heat generated by the drive motor 2 is conducted to the tank wall, the air flows in the numerous hexagonal hollows, forming a dense airflow network, which quickly transfers the heat to the mosquito repellent bottle 4. Moreover, the honeycomb structure helps to distribute the heat evenly, avoids local temperature being too high or too low, and ensures that the mosquito repellent liquid evaporates continuously and stably.

[0071] The implementation method of Example 16 is as follows: Example 16, based on Example 4, also has the following implementation method: The mosquito repellent bottle 4 is made of food-grade stainless steel. Food-grade stainless steel has good thermal conductivity, stable chemical properties, will not release harmful substances within the temperature range of the fan's operation, and is resistant to high temperature and not easily corroded. It will not react chemically with the mosquito repellent liquid, and is highly safe.

[0072] The implementation method of Example 17 is as follows: The difference between Example 17 and Example 16 is that the mosquito repellent bottle 4 is made of high borosilicate glass. High borosilicate glass has moderate thermal conductivity and good light transmittance, making it easy to observe the remaining amount of mosquito repellent liquid. Its material is stable and non-toxic, and it will not produce substances harmful to the human body even when heated. Moreover, its surface is smooth and easy to clean, which can prevent the growth of bacteria due to mosquito repellent liquid residue.

[0073] The implementation method of Example 18 is as follows: The difference between Example 18 and Example 7 is that the length of the motor mounting housing 1 along the horizontal direction is 160mm. When the length of the motor mounting housing 1 along the horizontal direction is 160mm, the distance between the fan heads on the left and right sides is at the smaller value within this range. This can avoid mutual interference of airflow caused by the distance being too close, ensure stable air output efficiency, and make the overall structure of the fan more compact.

[0074] The implementation method of Example 19 is as follows: The difference between Example 19 and Example 7 is that the length of the motor mounting housing 1 along the horizontal direction is 200mm. When the length of the motor mounting housing 1 along the horizontal direction is 200mm, the distance between the fan heads on the left and right sides is larger, and the airflow on both sides has more independent diffusion space, which can further reduce the possibility of airflow collision and cancellation, and the stability of the air output efficiency is stronger. The larger distance allows the fan to deliver air over a wider range.

[0075] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
