Description

Technical Field

[0001] The invention relates to the technical field of mosquito killing tools, in particular to an air suction type electric mosquito swatter. Background Art

[0002] Traditional electric mosquito swatters usually kill mosquitoes through a high-voltage metal net. Its structure mainly includes a net racket with a metal net and a racket handle for holding. Although this design can kill mosquitoes to a certain extent, there are many problems in actual use. First of all, traditional electric mosquito swatters mainly rely on manual swinging to catch mosquitoes. When a mosquito touches the metal net, due to the rapid swinging of the electric mosquito swatter, the mosquito's body may bounce out of the net racket range due to inertia, resulting in the mosquito not being effectively killed or escaping. In addition, when the mosquito approaches but does not completely enter the metal net range, it may also escape due to airflow or other interference. Summary of the invention

[0003] The purpose of the present invention is to provide a wind-suction type electric mosquito swatter to solve the problem of mosquito escape in traditional electric mosquito swatters.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a suction-type electric mosquito swatter, comprising a handle and a swatter provided with a metal mesh, wherein the inner side of the swatter is provided with a suction gap facing the front of the swatter, and is equipped with a suction device; the suction device sucks the area in front of the swatter through the suction gap to form a low-pressure area and generate an inward airflow; the inward airflow attracts mosquitoes and forms an airflow barrier around the metal mesh to prevent the mosquitoes from escaping.

[0005] Furthermore, a guide surface is provided on the side wall of the suction gap near the center of the racket, and the front end of the guide surface is inclined toward the center of the racket, so that the air in the area in front of the racket that at least partially overlaps with the metal mesh can be sucked by the suction device, thereby forming an additional airflow barrier in front of the metal mesh.

[0006] Furthermore, the additional airflow barrier forms a closed structure in front of the metal mesh, and together with the metal mesh constitutes a closed cage structure.

[0007] Furthermore, an airflow cavity connected to the air suction gap is provided in the racket, and the cross-sectional area of ​​the airflow cavity is larger than the cross-sectional area of ​​the air suction gap, and the suction device sucks the area in front of the racket through the airflow cavity via the air suction gap.

[0008] Furthermore, the air suction gap is formed into a continuous annular structure along the inner side of the racket.

[0009] Furthermore, a mounting cavity connected to the airflow cavity is provided in the handle, a through hole is provided on the handle, the through hole connects the mounting cavity with the outside, and the suction device is installed in the mounting cavity.

[0010] Furthermore, at least one side of the metal mesh is provided with a protective mesh, wherein the meshes of the metal mesh and the meshes of the protective mesh can be aligned or staggered, preferably staggered.

[0011] Furthermore, the electric mosquito swatter has a manual mosquito killing mode and a static mosquito killing mode; In manual mosquito killing mode, the metal mesh continuously discharges electricity and the suction device operates at a high wind speed to increase the probability of hitting mosquitoes; In the static mosquito killing mode, the metal mesh continues to discharge within the preset time, and the suction device runs at a lower wind speed to reduce noise; if no current pulse change is detected in the metal mesh within the preset time, the mosquito killing work is determined to be completed. At this time, the wind speed of the suction device is adjusted to a lower speed, and the power supply of the metal mesh is turned off to save energy; when the current pulse is detected again, the power supply of the metal mesh is restarted and the wind speed of the suction device is increased.

[0012] The present invention forms a low-pressure area in the air suction gap and the area in front of the net racket through the suction device and generates an inward airflow, thereby attracting mosquitoes into the metal net area, improving the success rate of capture, and forming an airflow barrier around the metal net to prevent mosquitoes from escaping, thereby solving the problem of mosquito escape in traditional electric mosquito swatters.

DETAILED DESCRIPTION

[0014] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0015] like Figure 1-5 As shown, the present embodiment provides a suction-type electric mosquito swatter, comprising a swatter 2 with a metal mesh 3 and a swatter handle 1 for holding. The metal mesh 3 is powered by a power supply and can release high voltage electricity to kill mosquitoes. A suction gap 2a facing the front of the swatter 2 is provided around the inner side of the swatter 2, and is equipped with a suction device 4, such as a micro fan such as a bladeless suction fan. The suction device 4 sucks the area in front of the swatter 2 through the suction gap 2a, forming a low-pressure area and generating an inward airflow. The inward airflow can attract mosquitoes into the metal mesh 3 area, and form an airflow barrier around the metal mesh 3, effectively preventing mosquitoes from escaping. Compared with traditional mosquito killing methods, the present embodiment significantly improves the hit rate of mosquitoes through the newly added suction function. At the same time, it adopts a physical mosquito killing method, which is safe and non-toxic, more environmentally friendly and healthy, and the airflow barrier formed can solve the problem of mosquito escape.

[0016] It should be noted that the low-pressure zone is mainly formed at the following two locations: First, a low-pressure zone is formed at the suction gap 2a. This is because the suction device 4 sucks the air through the suction gap 2a, and directly generates a low-pressure zone at the entrance of the suction gap 2a. This low-pressure zone is the starting point for the formation of the airflow and the initial power source for attracting mosquitoes. Its function is to attract mosquitoes to the vicinity of the suction gap 2a, creating conditions for subsequent capture. Secondly, the low-pressure zone is further extended to the area in front of the net racket 2. When the suction device 4 is running, the air in front of the net racket 2 is sucked through the suction gap 2a, so that the air in front of the net racket 2 is sucked into the suction gap 2a, thereby forming a low-pressure zone in front of the net racket 2. This low-pressure zone can attract mosquitoes to the metal mesh 3 area, and guide the mosquitoes to the vicinity of the metal mesh 3 through the inward airflow, increasing the probability of mosquitoes contacting the metal mesh 3. Therefore, the low-pressure area is mainly formed at the air suction gap 2a (this is the starting point of the low-pressure area, which is directly generated by the suction action of the suction device 4) and the area in front of the racket 2 (this is the extension area of ​​the low-pressure area, which is formed by sucking the air in front of the racket 2). The low-pressure areas at these two locations work together to achieve the function of attracting mosquitoes and preventing them from escaping.

[0017] In this embodiment, a guide surface 2a1 is provided on the side wall of the air suction gap 2a near the center of the racket 2, and the front end of the guide surface 2a1 is inclined toward the center of the racket 2. Figure 4. This design adjusts the suction direction so that the air in the area in front of the net racket 2 that at least partially overlaps with the metal mesh 3 can be sucked by the suction device 4, thereby forming an additional airflow barrier in front of the metal mesh 3. In this way, the guide surface 2a1 not only enhances the stability of the airflow barrier, but also further increases the probability of attracting mosquitoes. Specifically, if the air suction gap 2a faces straight forward, the airflow barrier is usually only formed on the outside of the metal mesh 3, and the coverage range is limited. By setting the guide surface 2a1 inclined toward the center of the net racket 2, an additional airflow barrier can be formed on the inside of the metal mesh 3, further expanding the coverage range of the airflow barrier, so that the entire metal mesh 3 area is surrounded by more effective airflow. This optimized design significantly improves the mosquito killing efficiency of the electric mosquito swatter, especially when catching fast-flying or evading mosquitoes, the effect is more obvious. In addition, by adjusting the inclination angle of the guide surface 2a1, the additional airflow barrier can form a closed structure in front of the metal mesh 3, and together with the metal mesh 3, it forms a closed cage structure, which can further enhance the capture effect of mosquitoes and prevent mosquitoes from escaping. When the suction device 4 is working, the air flow direction in the area in front of the racket 2 can be seen from Figure 5 .

[0018] In this embodiment, the racket 2 is provided with an airflow cavity 2b connected to the air suction gap 2a, and the cross-sectional area of ​​the airflow cavity 2b is larger than the cross-sectional area of ​​the air suction gap 2a. Figure 4 . The suction device 4 suctions the area in front of the net racket 2 through the air suction gap 2a via the air flow cavity 2b. The main purpose of this design is to optimize the suction effect. Since the air suction gap 2a surrounds the net racket 2 and covers a large area, direct air suction only through the air suction gap 2a may result in poor suction effects in certain areas. By setting an air flow cavity 2b with a larger cross-sectional area and using it as a buffer area, the suction device 4 can first extract the air in the air flow cavity 2b, and use the time difference to effectively suck the air in the entire air suction gap 2a. This design not only improves the suction efficiency, but also ensures that the airflow distribution in the entire net racket 2 area is more uniform, thereby more effectively attracting mosquitoes into the metal mesh 3 area and killing them.

[0019] In this embodiment, the air suction gap 2a is formed into a continuous annular structure along the inner side of the net racket 2. The annular structure completely surrounds the peripheral area of ​​the metal mesh 3. This design forms a relatively closed air flow channel around the entire metal mesh 3, ensuring that the air flow can be evenly and continuously sucked into the air suction gap 2a from the front area of ​​the net racket 2. Through this annular structure, the suction device 4 can form a stable low-pressure area around the entire periphery of the metal mesh 3, thereby more effectively attracting mosquitoes into the metal mesh 3 area and preventing mosquitoes from escaping from any direction.

[0020] In this embodiment, a mounting cavity 1a is provided in the handle 1, and the mounting cavity 1a is connected to the airflow cavity 2b, and the airflow cavity 2b is connected to the air suction gap 2a. The suction device 4 is installed in the mounting cavity 1a, and the airflow cavity 2b sucks the front area of ​​the racket 2 through the airflow gap 2a to form a low-pressure area, thereby attracting mosquitoes to enter the metal net 3 area. The handle 1 is provided with a plurality of through holes 1a1, which are spaced apart on the rear side of the handle 1 to form a fence structure. The function of the through holes 1a1 is to discharge the air in the mounting cavity 1a to maintain the normal operation of the suction device 4 and ensure the stability of the suction effect.

[0021] In this embodiment, at least one side of the metal mesh 3 is provided with a protective mesh 5, which can be provided on the front side, the rear side, or both sides of the metal mesh 3 to prevent users from accidentally contacting the metal mesh 3. The meshes of the metal mesh 3 and the meshes of the protective mesh 5 can be aligned or staggered, but staggered is preferred. This is because staggered meshes can effectively reduce physical barriers, making it easier for mosquitoes to contact the high-voltage power grid, thereby improving the mosquito killing effect.

[0022] In this embodiment, the electric mosquito swatter can be equipped with a mosquito-attracting lamp to enhance the mosquito killing effect. For example, a blue light mosquito-attracting lamp can be set on the net swatter 2. This design can more effectively attract mosquitoes in a dark environment, thereby improving the mosquito killing efficiency. The mosquito-attracting lamp can be an LED blue light strip and arranged along the air suction gap 2a.

[0023] In this embodiment, the electric mosquito swatter has intelligent mosquito killing modes, including a manual mosquito killing mode and a static mosquito killing mode.

[0024] In the manual mosquito killing mode, the user swings the electric mosquito swatter, the metal mesh 3 continuously discharges electricity, and the suction device 4 operates at a high wind speed to increase the probability of hitting mosquitoes. This mode is suitable for scenarios where the user actively captures mosquitoes (mainly mosquitoes), and the capture efficiency is significantly improved through high wind speed and continuous discharge.

[0025] In the static mosquito killing mode, the electric mosquito swatter is placed in the mosquito killing area, the metal mesh 3 continues to discharge within the preset time, and the suction device 4 runs at a lower wind speed to reduce noise. This mode is suitable for the scenario where the user places the electric mosquito swatter in a specific area and lets it run automatically. If no current pulse change is detected in the metal mesh 3 within the preset time, it is determined that the mosquito killing work is completed. At this time, the wind speed of the suction device 4 is adjusted to a lower speed, and the power supply of the metal mesh 3 is turned off to save energy. When the current pulse is detected again, the power supply of the metal mesh 3 is restarted and the wind speed of the suction device 4 is increased.

[0026] It should be noted that when the electric mosquito swatter is in a static mosquito killing mode, its air suction gap 2a and guide surface 2a1 are designed to form an airflow barrier and together with the metal mesh 3 form a closed cage structure. This design can effectively prevent mosquitoes from escaping when approaching the metal mesh 3, thereby significantly increasing the probability of mosquitoes contacting the power grid. In addition, the air suction type electric mosquito swatter is also equipped with a mosquito attracting lamp, and the light emitted by the mosquito attracting lamp can attract mosquitoes to approach the electric mosquito swatter. Combined with the air suction function, mosquitoes are more likely to be guided to the vicinity of the metal mesh 3, and then electrocuted to death. Therefore, the mosquito killing effect of the air suction type electric mosquito swatter is significantly better than that of the traditional electric mosquito swatter. Its air suction device can not only suck in and fix mosquitoes near the metal mesh 3, but even if the mosquitoes are not directly sucked into the power grid, the chance of contact with the power grid will be increased due to the guidance of the airflow.

[0027] In this embodiment, the overall structure of the electric mosquito swatter is composed of a net swatter 2 and a swatter handle 1. Figure 3 As shown, the net racket 2 is divided into a front racket portion 2n and a rear racket portion 2m, and the racket handle 1 is divided into a front handle portion 1n and a rear handle portion 1m. The front racket portion 2n of the net racket 2 is connected to the front handle portion 1n of the racket handle 1 through an integrated design to form the front end structure of the electric mosquito swatter; the rear racket portion 2m of the net racket 2 is connected to the rear handle portion 1m of the racket handle 1 through an integrated design to form the rear end structure of the electric mosquito swatter. This design makes the connection between the net racket 2 and the racket handle 1 more stable, and at the same time optimizes the overall structure of the electric mosquito swatter. The front racket portion 2n and the rear racket portion 2m, as well as the front handle portion 1n and the rear handle portion 1m, are installed in a detachable connection (such as a snap-on structure) to form a complete net racket 2 and racket handle 1 structure. Among them, after the front racket portion 2n and the rear racket portion 2m are assembled, two independent chambers can be formed on the net racket 2: an airflow chamber 2b (air suction area) and a wiring chamber 2c (wiring area). The airflow cavity 2b and the wiring cavity 2c are separated by an isolation rib plate 10. The isolation rib plate 10 is divided into two parts, which are respectively arranged on the front part 2n and the rear part 2m, and are sealed after assembly. The airflow cavity 2b is connected to the outside through the air suction gap 2a inside the front part 2n, and is connected to the installation cavity 1a in the handle 1; the wiring cavity 2c is connected to the control cavity 1b in the handle 1, and the control cavity 1b is used to install components such as the power supply 8 and the controller 7. Through this design, the internal structure of the front part 2n and the rear part 2m realizes the separation of the wiring area and the air suction area, forming a closed environment of the air suction area, thereby ensuring the air suction effect and efficiency. At the same time, the front part 2n and the rear part 2m can form an air suction gap 2a and a suitable air suction angle after assembly. The air outlet fence (through hole 1a1) on the handle 1 further optimizes the airflow path, so that the air suction function is realized on the capture target surface, and the air outlet function is realized on the capture target back. In addition, in order to improve convenience, the size of the handle 1 and the net racket 2 can be designed to be ergonomic and convenient for hand-held use. The overall structure is compact, which reduces space waste and facilitates reducing the size of the electric mosquito swatter, making it easier to operate and carry.

[0028] like Figure 3 , 4 As shown, an annular positioning member 6 is provided on the inner side of the net racket 2, and the annular positioning member 6 can be fixedly connected to the net racket 2 or detachably connected. A plurality of positioning grooves are provided around the inner side of the annular positioning member 6, and these grooves correspond to the number of the metal mesh 3 and the protective mesh 5, and are used to position and install the metal mesh 3 and the protective mesh 5. Matching connection holes are provided on the annular positioning member 6 and the net racket 2, which are used to connect the line connected to the metal mesh 3 to the control circuit in the wiring cavity 2c. In this embodiment, a layer of metal mesh 3 and two layers of protective mesh 5 are provided on the net racket 2, and the metal mesh 3 is located between the two layers of protective mesh 5, as can be seen in FIG. Figure 1 , 2 、4.

[0029] Among them, a plurality of buttons 9 are arranged on the handle 1, which are used to control various functions of the electric mosquito swatter, including the power switch and voltage control of the metal mesh 3, the switch and wind speed control of the suction device 4, the switch of the mosquito trap, etc. A controller 7 (such as an STM32F103 microcontroller) is arranged in the handle 1, which is used to control various functions of the electric mosquito swatter and realize different mosquito killing modes. In addition, a power supply 8 is also arranged in the handle 1, which is used to supply power to components such as the metal mesh 3, the suction device 4, and the mosquito trap. The power supply 8 is a rechargeable built-in battery, which reduces the trouble and cost of replacing the battery, and is equipped with a dedicated charger 11. The electric mosquito swatter is also equipped with a sensor for detecting the current pulse of the metal mesh 3, and is also equipped with a mosquito trap switch system, a timing system, a transformer circuit system, and a fan switch system. These systems are uniformly controlled and adjusted by the microcontroller, and all functions can be operated by the buttons 9 on the handle 1.

[0030] In general, the present invention forms a low-pressure area in the suction gap 2a and the area in front of the net racket 2 through the suction device 4 and generates an inward airflow, thereby attracting mosquitoes into the metal mesh 3 area, improving the success rate of capture, and forming an airflow barrier around the metal mesh 3, effectively preventing mosquitoes from escaping, thereby solving the problem of mosquito escape in traditional electric mosquito swatters.

[0031] Traditional electric mosquito swatters rely on manual waving to catch mosquitoes, which requires high skills and reaction speed of the user, resulting in low capture efficiency. In contrast, the suction-type electric mosquito swatter of the present invention actively attracts mosquitoes through inward airflow, reducing the reliance on manual operation of the user. Even when mosquitoes fly quickly or evade, the electric mosquito swatter can lead mosquitoes into the metal mesh 3 area and kill them, thereby significantly improving the capture efficiency.

[0032] Traditional electric mosquito swatters need to be frequently swung manually, and long-term use will cause user fatigue, and the problem of mosquitoes escaping will also affect the user experience. In contrast, the suction-type electric mosquito swatter of the present invention can actively attract mosquitoes into the metal mesh 3 area by setting a suction gap 2a facing the front of the net swatter 2 on the inner side of the net swatter 2 and equipping it with a suction device 4. This design reduces the frequency of manual operation and reduces user fatigue. At the same time, it prevents mosquitoes from escaping by forming a low-pressure area and an airflow barrier, significantly improving the success rate of capture and optimizing the user experience.

[0033] The above is only the preferred implementation of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as the preferred embodiment as above, it is not used to limit the product form and style of the present invention. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments with equivalent changes without departing from the scope of the technical solution of the present invention.
