A mosquito-killing device for epidemic prevention

Abstract

This invention discloses a mosquito-killing device for epidemic prevention, belonging to the field of mosquito-killing devices. It includes a mosquito-killing lamp and an outer frame. The mosquito-killing lamp is installed inside the outer frame, and a supporting base rod is installed on the bottom side of the outer frame. It should be noted that in this invention, when the outer expansion plate is accidentally stepped on, during heavy rain, or in flooded conditions, the four side sealing plates seal the mosquito-killing lamp. Under normal operating conditions, the side sealing plates are fully open and unobstructed, without affecting the propagation of the mosquito-attracting light or the entry of mosquitoes, thus preserving the core mosquito-attracting and mosquito-killing performance of the lamp. This completely solves the industry pain point that the fixed installation of conventional protective nets affects the mosquito-killing effect. Furthermore, the highly redundant progressive protection capability, in water accumulation scenarios, adopts a graded protection design of first stabilizing the base and then sealing the entire machine, forming a double safety redundancy. This avoids chain safety accidents caused by the failure of a single protection, significantly improving the equipment's survivability and safety baseline in extreme water accumulation and flood scenarios.

Description

Technical Field

[0001] This invention relates to the field of mosquito control devices, and more particularly to a mosquito control device for epidemic prevention. Background Technology

[0002] Mosquitoes are important vectors for diseases such as dengue fever, Zika virus, and chikungunya. Since there are currently no vaccines or specific drugs for most of these diseases, the core of prevention and control lies in "cutting off the transmission route." Mosquito lamps are an auxiliary tool among physical control methods. Mosquito lamps utilize mosquitoes' phototaxis and sensitivity to carbon dioxide and body temperature. They use UVA light of a specific wavelength to simulate human signals, attracting mosquitoes to approach and then killing them by electric shock, sticky trap, or airflow. The entire process does not require chemical agents and is suitable for long-term use in homes and communities.

[0003] Mosquito killer lamps are typically placed in areas with people and vegetation, such as residential communities. Therefore, there is a persistent problem of children or small animals accidentally touching them. The conventional solution is to add a fixed protective net. However, if the mesh is too large, it cannot prevent children's fingers or small animals from touching the high-voltage grid, leading to electric shock accidents. Conversely, if the mesh is too small, it obstructs the mosquito-attracting light, affecting the mosquito-killing effect. Furthermore, during heavy rain, if the mosquito killer lamp is located in a low-lying area, the stability of the conventional base decreases drastically under the buoyancy and scouring of the water, making it prone to tipping over, shifting, or even being washed away. Flooding can also directly cause short circuits, electrical leaks, and electrified water, posing significant safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a mosquito-killing device for epidemic prevention, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A mosquito-killing device for epidemic prevention includes a mosquito-killing lamp and an outer frame. The mosquito-killing lamp is installed inside the outer frame, and a supporting base rod is installed on the bottom side of the outer frame. It also includes an outward-expanding anti-accidental-touch mechanism, which is installed on the outer frame and is used to isolate and protect the mosquito killer lamp. The outward-expanding anti-accidental-touch mechanism includes four side sealing plates, which are rotatably installed on the four sides of the outer frame. Synchronous lifting pull seats are provided at the four corners of the outer frame. A rolling pressure rod is rotatably installed between two adjacent synchronous lifting pull seats. When the synchronous lifting pull seats move down, the rolling pressure rod drives the side sealing plates to rotate, thereby sealing the mosquito killer lamp. Furthermore, a pull-down bracket is installed on the four synchronous lifting pull seats, and a stepping outward-expanding plate is installed on the pull-down bracket. A water accumulation lifting protection structure is installed on the supporting base rod, which is used to lift the supporting base rod. The water accumulation lifting protection structure includes a water accumulation float plate, which is installed on the supporting base rod. A mounting base is movably installed on the bottom side of the supporting base rod. The mounting base is inserted into the ground, and a mounting plate is installed on the mounting base. The mounting plate is placed on the ground. The water accumulation float plate floats upward under force, which drives the outer frame to move upward through the supporting base rod, thereby driving the mosquito killer lamp to move upward actively. Pads are installed at the four corners of the top side of the mounting plate.

[0007] Furthermore, in a preferred embodiment of the present invention, the outward expansion anti-accidental touch mechanism further includes a top support plate, which is movably installed inside the outer frame, and all four synchronous lifting pull seats are installed on the top support plate; Both sides of the two adjacent synchronous lifting pull seats are provided with side mounting grooves, and the two ends of the rolling pressure rod are respectively rotatably installed in the two side mounting grooves.

[0008] Furthermore, in a preferred embodiment of the present invention, both sides of the side sealing plate are provided with a sealing rotating seat, and the sealing rotating seat is mounted on the outer frame; The side sealing plate is provided with a rotating mounting groove, and a rotating mounting shaft is rotatably installed in the rotating mounting groove. The two ends of the rotating mounting shaft are respectively installed on the two closed rotating seats. A torsion spring is installed on the inner wall of the rotating mounting groove, and the torsion spring is mounted on the rotating mounting shaft.

[0009] Furthermore, in a preferred embodiment of the present invention, a support spring is installed on the bottom side of the pull-down bracket, and the support spring is mounted on the support base rod.

[0010] Furthermore, in a preferred embodiment of the present invention, the water accumulation lifting protection structure further includes two transverse locking rods, and both sides of the mounting base are provided with pull holes, and the two transverse locking rods are respectively movably installed in the two pull holes; An outer pull plate is installed on the transverse locking rod, and an outer pull spring is installed between the outer pull plate and the inner wall of the mounting base.

[0011] Furthermore, in a preferred embodiment of the present invention, a snap-fit ​​bracket is installed on the top inner wall of the support base, and the snap-fit ​​bracket is inserted into the mounting base; The bottom side of the clip frame has a clip slot, and both of the outer pull plates are clipped into the clip slot.

[0012] Furthermore, in a preferred embodiment of the present invention, a flooding sealing protection mechanism is also included. The flooding sealing protection mechanism is installed on the water accumulation lifting protection structure, and the flooding sealing protection mechanism is connected to the outward expansion anti-accidental touch mechanism. The flooding sealing protection mechanism is used to drive the outward expansion anti-accidental touch mechanism to seal the mosquito killer lamp. The flooding sealing protection mechanism includes four active pressure rods, which are rotatably installed around the top side of the water-accumulating float. The pressing expansion plate is movably installed on the four active pressure rods. The rotation of the active pressure rods drives the pressing expansion plate to move, thereby rotating the four side sealing plates and sealing the mosquito-killing lamp.

[0013] Furthermore, in a preferred embodiment of the present invention, two downward pressure connecting seats are rotatably mounted on the active pressure rod, and one of the downward pressure connecting seats is mounted on the side sealing plate; A downward pressure drive shaft is rotatably mounted on the downward pressure connecting seat, and the downward pressure drive shaft is rotatably mounted on the active pressure rod.

[0014] Furthermore, in a preferred embodiment of the present invention, a descending connecting hole is provided around the top side of the water-accumulating float plate, and a descending seat is movably installed in the descending connecting hole, and another descending connecting seat is installed on the descending seat; The bottom of the water-collecting float is equipped with a descent box around its perimeter. A return spring is installed on the inner wall of the bottom of the descent box and is mounted on the descent seat.

[0015] Furthermore, in a preferred embodiment of the present invention, a downward pressing shaft is installed on the active pressing rod, and a downward pressing groove is provided on the downward pressing connecting seat, and the downward pressing shaft is rotatably installed in the downward pressing groove; A locking seat is installed at one end of the pressing shaft, and a locking hole is provided on the locking seat. A locking rod is inserted into the locking hole, and the locking rod is installed on the mounting base plate. A downward pressure torsion spring is installed on the downward pressure shaft, and the downward pressure torsion spring is installed on the inner wall of the downward pressure groove.

[0016] The beneficial effects of the mosquito-killing device for epidemic prevention proposed in this invention are: In this invention, the outward-expanding anti-accidental-touch mechanism ensures that when the outward-expanding plate is accidentally stepped on, the pressure causes the pull-down bracket to move downwards. This movement causes four synchronously lifting pull seats to move downwards, which in turn causes four rolling pressure rods to move downwards. The rolling pressure rods then push the side sealing plates to rotate, thus sealing the mosquito-killing lamp. Furthermore, during heavy rain, a direct impact on the top support plate can also move the four synchronously lifting pull seats, thereby sealing the mosquito-killing lamp and providing full protection. Under normal operating conditions, the side sealing plates can be fully opened without obstruction, ensuring the propagation of the mosquito-attracting light and preventing mosquitoes from entering, thus preserving the core mosquito-attracting and killing performance of the lamp. This completely solves the industry pain point that fixed protective netting installations affect mosquito-killing effectiveness.

[0017] Furthermore, in this invention, by setting up a water-lifting protection structure, when water accumulates at the location where the mosquito killer lamp is installed, the water-accumulating float is lifted by force, thereby causing the water-accumulating float to move the support base upward. The support base moves vertically upward on the mounting base, thereby causing the support base to move the mosquito killer lamp upward through the outer frame, thus avoiding the problem of the mosquito killer lamp being flooded. At the same time, when the support base moves upward, the two horizontal locking rods pop out, thereby improving the grip of the support base and avoiding the problem of the support base not being able to be stably installed due to water accumulation.

[0018] Furthermore, in this invention, by setting up a flood-sealing protection mechanism, as the water level continues to rise, the floating plate continuously moves upward, causing multiple downward-pressing connecting seats to move upward continuously. This causes the locking rod to disengage from the locking rotating seat, thereby causing the pressing expansion plate to move downward. The pressing expansion plate, through the pull-down bracket, causes four synchronous lifting pull seats to move downward, thereby causing the four side sealing plates to seal the mosquito killer lamp, preventing water from entering the mosquito killer lamp bulb during flooding, thus avoiding problems such as short circuits and leakage. In addition, through highly redundant progressive protection, the mosquito killer lamp adopts a graded protection design of first stabilizing the base and then sealing the entire machine in flood scenarios, forming a double safety redundancy, avoiding chain safety accidents caused by the failure of a single protection, and greatly improving the equipment's survivability and safety baseline in extreme flood scenarios.

[0027] Please refer to the attached instruction manual. Figures 1-11The present invention provides a mosquito-killing device for epidemic prevention, which includes a mosquito-killing lamp 1 and an outer frame 2. The mosquito-killing lamp 1 is installed inside the outer frame 2, and a supporting bottom rod 3 is installed on the bottom side of the outer frame 2. It also includes an outward expansion anti-accidental contact mechanism 4, which is installed on the outer frame 2 and is used to isolate and protect the mosquito-killing lamp 1. Specifically, the outward expansion anti-accidental contact mechanism 4 includes four side sealing plates 401, which are rotatably installed on the four sides of the outer frame 2. The four corners of the outer frame 2 are provided with synchronous lifting pull seats 406. A rolling pressure rod 407 is rotatably installed between two adjacent synchronous lifting pull seats 406. When the synchronous lifting pull seats 406 move down, the side sealing plates 401 are rotated through the rolling pressure rod 407 to close the mosquito killer lamp 1. Furthermore, a pull-down bracket 408 is installed on the four synchronous lifting pull seats 406, and a stepping outward expansion plate 411 is installed on the pull-down bracket 408. It should be noted that, in this embodiment of the invention, when the outer expansion plate 411 is stepped on, stepping on the outer expansion plate 411 causes the lower pull bracket 408 to move downward, thereby causing the four side sealing plates 401 to seal the mosquito killer lamp 1, preventing the mosquito killer lamp 1 from being accidentally touched by small animals or children, thus avoiding safety accidents; in addition, in heavy rain, directly impacting the top support plate 410 can also cause the four synchronous lifting pull seats 406 to move, thereby achieving the purpose of sealing the mosquito killer lamp 1 and achieving full protection for the mosquito killer lamp 1.

[0028] More specifically, in this embodiment of the invention, a water accumulation lifting protection structure 5 is installed on the supporting base rod 3. The water accumulation lifting protection structure 5 is used to lift the supporting base rod 3. The water accumulation lifting protection structure 5 includes a water accumulation float 501, which is installed on the supporting base rod 3. A mounting base 503 is movably installed on the bottom side of the supporting base rod 3. The mounting base 503 is inserted into the ground, and a mounting base plate 502 is installed on the mounting base 503. The mounting base plate 502 is placed on the ground. The water accumulation float 501 floats upward under the force, which drives the outer frame 2 to move upward through the supporting base rod 3. This is used to drive the mosquito killer lamp 1 to move upward actively. Pads 508 are installed at the four corners of the top side of the mounting base plate 502. It should be noted that in this embodiment of the invention, when water accumulates at the location where the mosquito killer lamp 1 is installed, the water accumulation float 501 is lifted by the force, causing the water accumulation float 501 to move the support base rod 3 upward, thereby causing the two horizontal locking rods 504 to pop out, which can improve the grip of the support base rod 3 and avoid the problem of the support base rod 3 being unable to be installed stably due to water accumulation.

[0029] Please refer to the instruction manual attached. Figures 2-7Furthermore, the mosquito-killing device for epidemic prevention provided in this embodiment of the invention includes an external anti-accidental contact mechanism 4, which also includes a top support plate 410. The top support plate 410 is movably installed inside the outer frame 2, and four synchronous lifting pull seats 406 are all installed on the top support plate 410. Furthermore, each of the two adjacent synchronous lifting pull seats 406 has a side mounting groove 412 on both sides, and the two ends of the rolling pressure rod 407 are respectively rotatably installed in the two side mounting grooves 412. It should be noted that in this embodiment of the invention, during heavy rain, a direct impact on the top bearing plate 410 can drive the four synchronous lifting pull seats 406 to move, thereby causing the four synchronous lifting pull seats 406 to drive the four rolling pressure rods 407 to move downward. The rolling pressure rods 407 push the side sealing plate 401 to rotate, thereby achieving the purpose of sealing the mosquito killer lamp 1. In addition, by covering the four core outdoor risks of accidental contact, heavy rain, water accumulation instability, and flooding short circuit, the protection level is improved from passive isolation protection to active trigger protection, which far exceeds the existing conventional outdoor mosquito killer lamps and effectively avoids the safety hazards of high voltage electric shock and leakage.

[0030] More specifically, in this embodiment of the invention, both sides of the side sealing plate 401 are provided with a closed rotating seat 402, and the closed rotating seat 402 is installed on the outer frame 2; the side sealing plate 401 is provided with a rotating mounting groove 403, and a rotating mounting shaft 404 is rotatably installed in the rotating mounting groove 403, and the two ends of the rotating mounting shaft 404 are respectively installed on the two closed rotating seats 402. Furthermore, a torsion spring 405 is installed on the inner wall of the rotating mounting groove 403, and the torsion spring 405 is mounted on the rotating mounting shaft 404. It should be noted that, in this embodiment of the invention, when the side sealing plate 401 is squeezed and rotated by the rolling pressure rod 407, it rotates on the rotating mounting shaft 404 through the rotating mounting groove 403, causing the torsion spring 405 to be stressed. Therefore, when the rolling pressure rod 407 resets, the torsional force of the torsion spring 405 can drive the side sealing plate 401 to reset.

[0031] More specifically, in this embodiment of the invention, a support spring 409 is installed on the bottom side of the pull-down bracket 408, and the support spring 409 is mounted on the support base rod 3. It should be noted that in this embodiment of the invention, the pull-down bracket 408 can be supported by the supporting force of the support spring 409.

[0032] Please refer to the instruction manual attached. Figures 2-4 and Figures 8-9 Furthermore, the mosquito-killing device for epidemic prevention provided in this embodiment of the invention includes a water accumulation lifting protection structure 5, which further includes two horizontal locking rods 504. Both sides of the mounting base 503 are provided with external pull holes 509, and the two horizontal locking rods 504 are respectively movably installed in the two external pull holes 509. In addition, an outer pull plate 505 is installed on the transverse locking rod 504, and an outer pull spring 506 is installed between the outer pull plate 505 and the inner wall of the mounting base 503. It should be noted that, in this embodiment of the invention, when water accumulates in the mosquito killer lamp 1, the snap-fit ​​bracket 507 is disengaged from the two outer pull plates 505. At this time, under the external pulling force of the two outer pull springs 506, the two transverse locking rods 504 pop out, thereby improving the grip of the support base rod 3 and avoiding the problem of unstable installation of the support base rod 3 due to water accumulation.

[0033] More specifically, in this embodiment of the invention, a snap-fit ​​bracket 507 is installed on the inner top wall of the support base 3, and the snap-fit ​​bracket 507 is inserted into the mounting base 503; a snap-fit ​​slot 510 is provided on the bottom side of the snap-fit ​​bracket 507, and both outer pull plates 505 are snapped into the snap-fit ​​slot 510. It should be noted that, in this embodiment of the invention, the snap-fit ​​bracket 507 snaps into the two outer pull plates 505 through the snap-fit ​​slot 510, thereby achieving the purpose of automatically separating from the two outer pull plates 505 when the snap-fit ​​bracket 507 moves upward.

[0034] Please refer to the instruction manual attached. Figures 2-3 and Figures 9-11 Furthermore, the mosquito-killing device for epidemic prevention provided in this embodiment of the invention also includes a flood-sealing protection mechanism 6. The flood-sealing protection mechanism 6 is installed on the water-lifting protection structure 5, and the flood-sealing protection mechanism 6 is connected to the outward expansion anti-accidental contact mechanism 4. The flood-sealing protection mechanism 6 is used to drive the outward expansion anti-accidental contact mechanism 4 to seal the mosquito-killing lamp 1. Specifically, the flood-sealing protection mechanism 6 includes four active pressure rods 601, which are rotatably mounted on the top periphery of the water-accumulating float 501. A pressing expansion plate 411 is movably mounted on the four active pressure rods 601. The rotation of the active pressure rods 601 drives the pressing expansion plate 411 to move, thereby rotating the four side sealing plates 401 and sealing the mosquito-killing lamp 1. It should be noted that in this embodiment of the invention, when the water level at the mosquito-killing lamp 1 continuously rises, the water-accumulating float 501 continuously moves upward, causing the active pressure rods 601 to automatically unlock and drive the pressing expansion plate 411 downward, thus sealing the mosquito-killing lamp 1 with the four side sealing plates 401. This prevents the mosquito-killing lamp 1 from being submerged in water, thus avoiding problems such as short circuits and electrical leakage.

[0035] More specifically, in this embodiment of the invention, two downward pressing connecting seats 602 are rotatably mounted on the active pressing rod 601, one of which is mounted on the side sealing plate 401; a downward pressing drive shaft 603 is rotatably mounted on the downward pressing connecting seat 602, and the downward pressing drive shaft 603 is rotatably mounted on the active pressing rod 601. It should be noted that, in this embodiment of the invention, when the active pressing rod 601 is unlocked, the downward pressing torsion spring 609 drives the downward pressing shaft 608 to rotate, causing the downward pressing shaft 608 to drive the active pressing rod 601 to rotate. The rotation of the active pressing rod 601 drives the other downward pressing connecting seat 602 to move downward through the downward pressing drive shaft 603, thereby achieving the purpose of actively moving the stepping expansion plate 411 downward.

[0036] Please continue to refer to the instruction manual appendix. Figures 2-3 and Figures 9-11 More specifically, in this embodiment of the invention, the top side of the water-accumulating float 501 is provided with a descending communication hole 613, and a descending seat 610 is movably installed in the descending communication hole 613, and another descending connecting seat 602 is installed on the descending seat 610. Furthermore, a lowering box 611 is installed around the bottom perimeter of the water-accumulating float 501. A return spring 612 is installed on the inner bottom wall of the lowering box 611, and the return spring 612 is mounted on the lowering seat 610. It should be noted that, in this embodiment of the invention, when the outer expansion plate 411 is pressed down, the lowering seat 610 is moved down by the pressing connecting seat 602, and the lowering seat 610 moves within the lowering box 611, thereby causing the return spring 612 to be stressed, thus achieving the purpose of not affecting the downward movement of the outer expansion plate 411.

[0037] More specifically, in this embodiment of the invention, a downward pressing shaft 608 is installed on the active pressing rod 601, and a downward pressing groove 607 is opened on the downward pressing connecting seat 602. The downward pressing shaft 608 is rotatably installed in the downward pressing groove 607. A locking rotating seat 604 is installed at one end of the downward pressing shaft 608, and a locking insertion hole 606 is opened on the locking rotating seat 604. A locking rod 605 is inserted into the locking insertion hole 606, and the locking rod 605 is installed on the mounting base plate 502. In addition, a downward pressure torsion spring 609 is installed on the downward pressure rotating shaft 608, and the downward pressure torsion spring 609 is installed on the inner wall of the downward pressure rotating groove 607. It should be noted that in this embodiment of the invention, the water level continues to rise, causing the water accumulation float 501 to move upward continuously. This causes the water accumulation float 501 to drive multiple downward pressure connecting seats 602 to move upward continuously, thereby causing the locking rod 605 to disengage from the locking rotating seat 604. At this time, under the torsional force of the downward pressure torsion spring 609, the downward pressure rotating shaft 608 is driven to rotate. The downward pressure rotating shaft 608 drives the active pressure rod 601 to rotate. The rotation of the active pressure rod 601 drives another downward pressure connecting seat 602 to move downward through the downward pressure driving shaft 603, thereby driving the stepping expansion plate 411 to move downward, so as to achieve the purpose of automatically unlocking the active pressure rod 601 when the water level rises.

[0038] In summary, the working principle of the mosquito-killing device for epidemic prevention provided in this embodiment of the invention is as follows: When a small animal or child accidentally steps on the extended plate 411, the extended plate 411 causes the pull bracket 408 to move downwards, which in turn causes the support spring 409 to contract under force. The downward movement of the pull bracket 408 causes the four synchronous lifting pull seats 406 to move downwards, which in turn causes the four synchronous lifting pull seats 406 to move the four rolling pressure rods 407 downwards. The rolling pressure rods 407 push the side sealing plate 401 to rotate. At the same time, the rolling pressure rods 407 rotate within the two side mounting slots 412. The 01 rotates on the rotating mounting shaft 404 through the rotating mounting slot 403, causing the rotating torsion spring 405 to be stressed, thereby causing the four side sealing plates 401 to seal the mosquito killer lamp 1, preventing small animals or children from accidentally touching it and causing safety accidents; in addition, in heavy rain, direct impact on the top support plate 410 can also drive the four synchronous lifting pull seats 406 to move, thereby achieving the purpose of sealing the mosquito killer lamp 1, thus achieving full protection for the mosquito killer lamp 1; Furthermore, when water accumulates at the location where the mosquito killer lamp 1 is installed, the water-accumulating float 501 floats upward under pressure, causing the support rod 3 to move upward. The support rod 3 moves vertically upward on the mounting base 503, thereby causing the support rod 3 to move the mosquito killer lamp 1 upward through the outer frame 2, preventing the mosquito killer lamp 1 from being flooded. At the same time, when the support rod 3 moves upward, it causes the snap-fit ​​bracket 507 to disengage from the two outer pull plates 505. At this time, under the external pulling force of the two outer pull springs 506, the two horizontal locking rods 504 pop out, thereby improving the grip of the support rod 3 and preventing the support rod 3 from being unstable due to water accumulation. Furthermore, if the water level continues to rise, causing the floating plate 501 to continuously move upward, it will cause multiple downward connecting seats 602 to continuously move upward, thereby causing the locking rod 605 to disengage from the locking rotating seat 604. At this time, under the torsional force of the downward torsion spring 609, the downward rotating shaft 608 will rotate, and the downward rotating shaft 608 will drive the active pressure rod 601 to rotate. The rotation of the active pressure rod 601 will drive another downward connecting seat 602 to move downward through the downward driving shaft 603, thereby driving the stepping expansion plate 411 to move downward. The stepping expansion plate 411 will drive four synchronous lifting pull seats 406 to move downward through the pull bracket 408, thereby causing the four side sealing plates 401 to seal the mosquito killer lamp 1, preventing the mosquito killer lamp 1 from being submerged in water and causing problems such as short circuits and leakage.
