Description

Technical Field

[0001] This utility model relates to the field of municipal engineering, specifically to a retractable mosquito-repellent street light. Background Technology

[0002] Mosquito-repellent streetlights are public facilities that integrate outdoor lighting and mosquito repellency. They are typically deployed in outdoor locations such as parks, community trails, and courtyards where both lighting and mosquito prevention are required. The basic structure consists of a storage device for mosquito repellent and a mosquito repellent dispersal mechanism added inside the pole of a traditional streetlight. Ideally, mosquito-repellent streetlights aim to create a relatively mosquito-free protective zone by releasing mosquito-repellent active ingredients in a timed and directional manner, thereby improving the comfort of the outdoor environment.

[0003] Currently, the mainstream method of mosquito repellent dispersal in this technical field is mist spraying. Specifically, liquid mosquito repellent is sprayed directly into the surrounding environment in the form of fine droplets through a built-in micro pump and atomizing nozzle. The advantage of this method is that it takes effect relatively quickly.

[0004] However, this method generally presents safety issues. Since the installation location and spraying angle of streetlights are usually fixed, mosquito repellent droplets sprayed from a height are easily blown down by wind or their own inertia. In pedestrian areas such as private courtyards or parks, these droplets containing chemicals are likely to be sprayed directly onto the face, eyes, or skin of passersby. Even if the mosquito repellent is of low toxicity, such contact can still cause skin irritation or allergic reactions in sensitive groups such as children and pregnant women.

[0005] While existing technologies include products that use electric heating devices to heat mosquito repellents, accelerating their evaporation into a gaseous state for diffusion, these products typically have heating devices added rather than being integrated with the streetlights themselves. In summer, these heating devices may cause the streetlights to overheat, posing a safety hazard. Utility Model Content

[0006] To address the safety hazards arising from the crude release methods of mosquito-repellent substances and the low integration of the lamp body in existing technologies, this application provides a retractable mosquito-repellent street light.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: A retractable mosquito-repellent street light includes a street light base and a retractable lamp post vertically mounted on the street light base, and a mosquito-repellent lamp head assembly mounted at the end of the lamp post; the mosquito-repellent lamp head assembly includes a lamp cover formed by a lamp head top cover and a hollow lamp wall, the inner side of the hollow lamp wall is provided with an installation groove for installing solid mosquito-repellent material, and the lamp cover also accommodates an air supply device and a lighting bulb arranged vertically opposite each other along the same vertical axis.

[0008] Furthermore, the air supply device is located in the center of the lamp head cover; the light bulb is mounted directly below the air supply device via a lamp holder with its light-emitting part facing the air supply device.

[0009] Furthermore, the inner wall of the lamp head cover is coated with a reflective layer.

[0010] Furthermore, the retractable lamp post consists of an outer tube and an inner tube inserted inside the outer tube and capable of retracting relative to the outer tube, with the outer tube fixed in the street light base.

[0011] Furthermore, the outer surface of the street light base is provided with a solar panel, and the interior is provided with a solar energy storage component, which is electrically connected to the lighting bulb, the air supply device, and the solar panel respectively.

[0012] Furthermore, the lampshade has a trapezoidal structure, and at least one side of the hollow lamp wall of the lampshade is provided with an openable and closable buckle structure.

[0013] Furthermore, the outer side of the hollowed-out lamp wall is covered with an insect-proof net, and the edge of the insect-proof net has magnetic strips that can be adsorbed and fixed onto the hollowed-out lamp wall.

[0014] Furthermore, the solar panel is also installed on the lamp post.

[0015] Furthermore, the street light base is provided with mounting holes for screws to pass through.

[0016] Beneficial effects: This invention utilizes a solid mosquito-repellent substance combined with a ventilation device to achieve natural evaporation, eliminating the need for traditional mist spraying or external heating methods. This avoids the safety hazards of direct contact between the mosquito repellent and pedestrians or the risk of overheating, significantly improving safety and user-friendliness. Furthermore, the retractable lamp post structure allows users to flexibly adjust the mosquito-repellent height according to actual needs, achieving optimal matching between the mosquito-repellent range and the lighting area, enhancing environmental adaptability. It also allows pedestrians passing by the streetlights to experience a cool breeze, significantly improving the comfort of the outdoor experience. In addition, this invention incorporates a solar power supply system, achieving functional integration and energy self-sufficiency, combining the practical advantages of high efficiency, energy saving, and easy maintenance. Its simple structure and convenient operation make it suitable for industrial promotion. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] Example 1: like Figures 1-3 As shown in the figure, this utility model discloses the specific structure of a retractable mosquito-repellent street light, including a street light base 1 and a retractable lamp post 3 vertically installed on the street light base 1, and a mosquito-repellent lamp head assembly 2 installed at the end of the lamp post 3; the mosquito-repellent lamp head assembly 2 includes a lamp cover formed by a lamp head top cover 21 and a hollow lamp wall 22, the inner side of the hollow lamp wall 22 is provided with an installation groove 25 for installing solid mosquito-repellent material, and the lamp cover also accommodates an air supply device 23 and a lighting bulb 4 arranged vertically opposite to each other along the same vertical axis.

[0026] Working principle and technical effects: This retractable mosquito-repellent street light works on the principle of a physical process based on the synergistic effect of various components within a specific structure. Specifically, in this embodiment, a solid mosquito-repellent substance is impregnated with a pyrethroid insecticide to form a solid volatile sheet. The evaporation temperature range matches the heat dissipation temperature of the light bulb 4 during operation. When common incandescent or halogen lamps are working, the surface temperature of the bulb can reach 60-200℃ or higher, depending on the wattage. Conventional streetlights are typically between 30W and 150W. If a 40W incandescent bulb is used as the light bulb in this embodiment… The specific wattage of the light bulb 4, with a surface temperature typically between 60-80 degrees Celsius, is sufficient to allow the solid mosquito repellent substance to evaporate within the confined space of the lampshade. The fixed mosquito repellent substance is installed in the mounting groove 25 inside the hollow lamp wall 22. The structure of the hollow lamp wall 22 is not limited; the lamp wall structure can be adapted to round, square, or other shapes, as long as it can achieve the basic functions of installing the mosquito repellent substance and providing ventilation and light transmission. The lampshade also houses the air supply device 23 and the light bulb 4, which are arranged opposite each other. This vertically opposed layout provides a structural basis for forming an efficient directional airflow path.

[0027] The air supply device 23 is at least one miniature soft-wind fan, which is prior art and will not be described in detail here.

[0028] During operation, the light bulb 4 is turned on first. In a preferred embodiment, the air supply device 23 is set to start after a delay period following the bulb's illumination. In this embodiment, this delay period is set to 3 minutes. When the delay period ends, the air supply device 23 automatically starts operating. This design is because the light bulb 4 needs a short time to reach a stable operating temperature and generate sufficient heat to fill the lampshade after it is lit, allowing the solid mosquito repellent substance to gradually evaporate. After the air supply device 23 is started, the airflow mainly flows through the area opposite to the air supply device 23. The installed light bulb 4 effectively cools the bulb, extending its lifespan. Furthermore, the airflow is heated by the bulb, becoming a warm, rising airflow. This hot airflow, blocked and guided by the lamp head cover 21, diffuses around the lampshade, i.e., towards the perforated lamp wall 22. During this flow, it thoroughly washes and heats the solid mosquito-repellent material installed on the side walls, greatly promoting the rapid and uniform evaporation of its effective components. Finally, this warm airflow, rich in mosquito-repellent components, is pushed out of the lamp through the perforated lamp wall 22 under wind pressure, forming a mosquito-repellent wind barrier.

[0029] The reason for choosing a fixed mosquito repellent substance instead of a liquid mosquito repellent liquid, which is theoretically more volatile, is that, compared with the easily leaked liquid mosquito repellent liquid, the solid substance has stable physical properties, does not require complex sealing, and has no risk of leakage and environmental pollution. At the same time, the solid form is also easier to transport, store and replace. By converting the waste heat of the bulb into an effective energy source that promotes the volatilization of the mosquito repellent substance, the efficient reuse of heat energy is achieved. Meanwhile, the air supply device 23 continuously dissipates heat from the bulb, which not only sends the mosquito repellent air out of the bulb, but also effectively reduces the working temperature of the bulb and extends the service life of the lighting bulb 4.

[0030] like Figure 6 As shown, in addition, through the design of the retractable light pole 3, staff can adjust it independently according to different scenarios, seasons and groups of people, in order to target mosquito habits or avoid the breathing height range of children and adults.

[0031] It is understandable that, for good thermal conductivity, the lampshade is preferably made of metal.

[0032] Example 2: like Figure 4 , Figure 5 As shown, this embodiment further optimizes the internal structure of the lamp head and the telescopic mechanism of the lamp post based on the first embodiment.

[0033] Specifically, in this embodiment, the lamp post 3 has a power supply interface 213 at its end to supply power to the mosquito repellent lamp head assembly 2. The air supply device 23 inside the mosquito repellent lamp head assembly 2 is installed in the center of the lamp head top cover 21. The lamp head top cover 21 has an installation strip 211 inside, and the installation strip 211 has installation holes. The lamp head top cover 21 can be installed together with the hollow lamp wall 22 by fasteners such as bolts. The lighting bulb 4 is installed directly below the air supply device 23 through the lamp holder 24 with the light-emitting part facing the air supply device 23. This layout makes the light-emitting part directly face the air outlet surface of the air supply device 23, thereby forming a highly directional airflow path inside the lamp cover. When the air supply device 23 is activated, the airflow first impacts the surface of the light-emitting part of the lamp bulb 4 vertically downwards. Since the light-emitting part is the main heat source area of ​​the bulb, this frontal impact achieves air cooling, thereby reducing the operating temperature of the bulb and extending its service life. At the same time, the airflow is heated by the bulb and rises rapidly, spreading outwards under the obstruction of the lamp head cover 21. Because the air supply device 23 is located in the center, the airflow distribution is more uniform, which can fully cover the solid mosquito-repellent material in the mounting groove 25 inside the hollow lamp wall 22, avoiding the problem of insufficient local evaporation, thereby improving the uniformity and efficiency of the mosquito-repellent ingredient evaporation. This centrally aligned layout also optimizes the space utilization inside the lamp cover, reduces airflow dead zones, and allows the warm airflow to be delivered more smoothly out of the lamp through the hollow structure, forming a stable mosquito-repellent air barrier.

[0034] Compared to a layout where the air supply device is positioned below and the light bulb above, the upper fan and lower bulb arrangement in this embodiment achieves better synergy. When the air supply device is located in the center of the lamp head cover and the bulb is directly below it, the airflow generated by the air supply device flows vertically from top to bottom, first directly acting on the surface of the bulb's light-emitting part, which has the highest temperature. After being heated by the bulb, this airflow, due to the natural upward convection tendency of hot air, forms a spiraling or swirling hot airflow field inside the lampshade, opposite to the direction of forced airflow but ultimately dominated by air pressure. This dynamic hot airflow field ensures that the hot air has a longer residence time and a more sufficient diffusion path inside the lampshade, thereby uniformly heating the entire interior space of the lampshade, especially the mosquito repellent material located on the side walls. This avoids the temperature stratification phenomenon of hot air accumulating at the top and the bottom being too cold, resulting in more uniform and stable volatilization of the mosquito repellent ingredients. Conversely, if a layout with a fan below and a bulb above is adopted, the cold air blows the bulb from bottom to top. The heated air will accelerate upwards due to natural convection and accumulate at the top of the lampshade, making it difficult to effectively flow back downwards to the area where the mosquito repellent material is installed. This can easily lead to a significant temperature difference between the upper and lower parts of the lampshade, creating a heat short-circuit effect. The heat cannot be effectively used to heat the mosquito repellent material on the side walls, but instead, most of it accumulates and dissipates at the top. This not only reduces the efficiency of heat utilization but may also pose a safety hazard due to localized overheating at the top. By utilizing the synergistic effect of forced convection and natural convection, rather than their mutual cancellation, efficient and uniform distribution and utilization of heat energy are achieved. This is a key technical effect that is difficult to achieve with a conventional layout where the fan is below and the bulb is above.

[0035] Furthermore, the inner wall 212 of the lamp head cover 21 is coated with a reflective layer, preferably a high-reflectivity metal coating. The reflective layer effectively reflects the light emitted upward by the lighting bulb 4 back downward, increasing the effective light intensity and illumination range of the street light. At the same time, the reflective layer can also reflect some heat radiation, helping to maintain the temperature stability inside the lamp cover and promoting the continuous volatilization of solid mosquito repellent substances. In addition, the telescopic lamp post 3 consists of an outer tube 33 and an inner tube 32 sleeved inside the outer tube 33. The inner tube 32 can extend and retract relative to the outer tube 33. A wire channel 31 is provided inside the inner tube 32. The outer tube 33 is fixed in the street light base 1. The height can be flexibly adjusted by bolt fastening or other fixing methods to adapt to different scene needs. For example, during the peak mosquito season in summer, the lamp head can be raised to expand the mosquito repellent coverage area, or it can be kept away from the height of children's activities to ensure safety.

[0036] It is understandable that this Embodiment 2 echoes Embodiment 1, continuing the concept of using waste heat from the bulb to promote the volatilization of mosquito-repellent substances. However, through the precise alignment of the air supply device 23 and the lighting bulb 4, the synergistic effect of airflow and heat is further enhanced. Furthermore, the delayed-start design of the air supply device 23 in Embodiment 1 is also applicable in this embodiment, but due to the more direct airflow path, higher heat exchange efficiency, faster volatilization rate of the mosquito-repellent substances, and better bulb heat dissipation, the overall energy efficiency is improved. Simultaneously, the refined design of the retractable lamp post 3 enhances the product's adaptability, consistent with the height adjustment function in Embodiment 1. In summary, this Embodiment 2, through structural optimization, achieves more efficient mosquito-repellent performance and reliability while maintaining the advantages of Embodiment 1.

[0037] Example 3: like Figures 1-3 As shown, this embodiment provides a further optimized implementation of a retractable mosquito-repellent street light, which integrates green energy, enhances ease of use and maintenance convenience based on the first and second embodiments.

[0038] The outer surface of the street light base 1 and the lamp post 3 are provided with solar panels 11, which integrate solar energy storage components, including batteries and charge / discharge controllers. Although not shown in the figure, these are very mature existing technologies, and the solar energy storage components are not the inventive point of this application, so they will not be described in detail here.

[0039] The solar energy storage component is electrically connected to the solar panel 11, the light bulb 4, and the ventilation device 23, forming an off-grid power supply system. This design enables the streetlights to achieve self-sufficiency using solar energy, a clean energy source, making it particularly suitable for locations such as parks and walkways where grid power access is inconvenient, thus enhancing the product's environmental adaptability and energy-saving characteristics. During the day, the solar panel 11 converts light energy into electrical energy and stores it in the battery. At night, the energy storage component provides power to the light bulb 4 and the ventilation device 23, achieving energy recycling.

[0040] The lampshade of the mosquito-repellent lamp head assembly 2 adopts a trapezoidal structure. This narrow-at-the-bottom and wide-at-the-top design forms a gradually narrowing airflow channel, which facilitates the smoother and wider diffusion of the airflow generated by the air supply device 23 after it shines downwards onto the bulb, thereby increasing the coverage area of ​​the mosquito-repellent airflow. At least one side of the hollow lamp wall 22 is designed to be opened and closed via a snap-fit ​​structure, allowing users or maintenance personnel to easily open the side of the lampshade for convenient replacement of the solid mosquito-repellent substance in the mounting slot 25 or for internal cleaning and maintenance.

[0041] To further enhance reliability, a fine insect-proof mesh (not shown in the figure) is covered on the outside of the perforated lamp wall 22. The edges of the insect-proof mesh are sewn or inlaid with magnetic strips, allowing it to be firmly and easily attached to the perforated lamp wall 22. This prevents moths, mosquitoes, and other insects from being attracted by the light and directly passing through the perforated structure into the lampshade, thus avoiding the accumulation of their corpses that could affect heat dissipation, optical performance, or even fan operation. At the same time, the magnetic attachment method allows the insect-proof mesh itself to be easily removed for cleaning or replacement.

[0042] In addition, a number of mounting holes 12 for screws are provided on the street light base 1. These mounting holes 12 allow the entire street light base 1 to be firmly installed on the cement foundation or other support surface using fasteners such as bolts, which enhances the stability and anti-overturning ability of the street light in the outdoor environment.

[0043] The working process of this utility model is as follows: When night falls, the solar energy storage component in the street lamp base 1 begins to supply power to the system. First, the lighting bulb 4 is lit, and the heat generated by the light accumulates inside the lamp cover, causing the internal temperature of the lamp cover to gradually rise. After a delay of about 3 minutes, when the temperature inside the lamp cover rises to the effective volatilization range, the solid mosquito repellent substance gradually volatilizes. At this time, the air supply device 23 installed in the center of the lamp head top cover 21 automatically starts.

[0044] The airflow generated by the air supply device 23 blows vertically downwards onto the surface of the light bulb 4, completing the initial air cooling. The heated airflow, blocked by the lamp head cover 21, then diffuses around the perforated lamp wall 22. During this process, it again washes over the solid mosquito-repellent material installed on the inner side, accelerating the evaporation of its active ingredients and forming a warm, mixed airflow rich in mosquito-repellent components. Finally, under the action of wind pressure, this airflow passes through the perforated lamp wall 22 and the insect-proof net on its outer side, evenly and continuously delivering it to the surrounding environment, providing illumination while forming a gentle mosquito-repellent wind barrier around the streetlight. The entire process achieves the synergy of waste heat utilization, forced convection cooling, and efficient evaporation of mosquito repellent, and the height adjustment of the extendable lamp post 3 adapts to different scenario needs.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
