Description

Technical Field

[0001] This invention relates to the field of mosquito control technology, specifically to a light-attracting mosquito control device for use in tent hospitals. Background Technology

[0002] Tent hospitals typically use tunnel tents or large-span flat-top tents. Tunnel tents are used to connect different modular units and serve as corridors, reception areas, or other functional areas. Large-span flat-top tents serve as bed areas, treatment areas, surgical areas, etc., providing more interior space. However, large-span flat-top tents, as areas where patients are concentrated, are more susceptible to mosquito infestations.

[0003] A search revealed Chinese patent CN114342894B, which includes a box body, a first storage chamber located on the box body, and a foldable and deployable tent frame located within the first storage chamber. Tent components are covered on the tent frame and can be folded or unfolded with the tent frame. Attraction holes are provided on the surface of the tent components, allowing insects to enter the tent components when they are unfolded. During use, when insects are attracted to the vicinity of the tent components by LED lights, a motor drives a fan to rotate, generating an inward airflow at the attraction holes, guiding the insects into the tent components. This significantly improves the efficiency of attracting insects while eliminating the need for on-site personnel to monitor the process, thus preventing insect bites.

[0004] However, the aforementioned patents use a single tent for mosquito trapping with lights. The installation process is cumbersome, and the size of the tent must be considered. If the tent is too small, the desired mosquito-killing effect will be difficult to achieve; if it is too large, it will consume too much land and thus lack practical significance. On the other hand, the aforementioned patents lack mosquito-killing methods after luring mosquitoes into the tent. With prolonged use, the number of mosquitoes inside the tent gradually increases. Due to their phototaxis, mosquitoes will largely block the LED lights, thus reducing the mosquito-trapping effect. Furthermore, the aforementioned patents use fans to create negative pressure inside the tent components. The size and power of the fans must also be considered. If the size and power are too small, the desired suction effect will be difficult to achieve; if the size and power are too large, noise and high power consumption will accompany the suction effect.

The top of the positioning rod is rotatably connected to a transmission wheel 2 via a pin. The transmission wheel 2 meshes with and is connected to the rack 1. The outer contour of the transmission wheel 2 near the guide rod is connected to a transmission wheel 1. The transmission wheel 1 also meshes with and is connected to the guide rod. The transmission wheel 1 and the rack 1 do not contact each other.

[0010] The follower component also includes a folding shaft that passes through and is rotatably connected to the end of rack one away from the adjusting roller. Rack two is also rotatably connected to the outer contour of the folding shaft, and rack two is toothed together with rack one. The end of rack two away from rack one is passed through and rotatably connected to a fixing clip that is snapped onto the tent frame to fix the device.

[0011] The pop-up mechanism includes a positioning plate that is penetrated and fixedly connected to a guide rod. A spline shaft is rotatably connected to the top of the positioning plate.

A follower ring is fixedly connected to the outer contour of the transmission ring and is penetrated and fixedly connected to the guide rod. A limit ring is fixedly connected to the top of the transmission ring. Limit pins are penetrated and fixedly connected to both sides of the outer contour of the limit ring.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] Please see Figures 1 to 9 The present invention provides a technical solution: a lamp-attracting mosquito-killing device for a tent hospital, including a fixed base 1 and a lifting assembly at its top, a follower assembly rotatably connected to both sides of the fixed base 1 and a trapping assembly set at the top of the lifting assembly, wherein a connecting rod 11 is fixedly connected to both sides of the fixed base 1, and a positioning seat 12 is fixedly connected to the end of the connecting rod 11 away from the fixed base 1.

[0033] The trapping assembly includes a blowing mechanism for completing the mosquito trapping and a spring-loaded mechanism for physically killing the captured mosquitoes. The blowing mechanism is located at the top of the lifting assembly and is fixedly connected to the lifting assembly. The spring-loaded mechanism is located inside the blowing mechanism and is drivenly connected to the blowing mechanism.

[0034] This device uses ultraviolet light of a specific wavelength to attract mosquitoes. When mosquitoes gather near the light source, they are guided and impacted by the airflow of the blowing mechanism, thus capturing them. Furthermore, the captured mosquitoes are physically killed by the rapid ejection of the popping mechanism.

[0035] It should be noted that the physical killing process of the pop-up mechanism is achieved by impact and crushing. Through the structural cooperation of the pop-up mechanism, the light source is gradually sealed before impact, thereby effectively overcoming the escape behavior of mosquitoes and improving the killing effect. On the other hand, while the pop-up mechanism is working, its reciprocating opening and closing motion simultaneously completes the wiping operation on the surface of the light source, thereby reducing the problem of mosquitoes attaching to the surface of the light source and causing obstruction, which leads to a decrease in the light attraction effect.

[0036] The lifting and following components work together to install the equipment. During installation, the lifting and following components work synchronously. The following components expand synchronously to adapt the equipment to the size and curvature of the tent top to meet the fixing process of different types of tents. The lifting component works synchronously and controls the height of the light source to minimize obstruction by the tent fabric and optimize the light source's attraction to mosquitoes. The fixing seat 1, connecting rod 11, and positioning seat 12 serve a positioning function, positioning the equipment at the center of the tent top to further optimize the diffusion range of the light source.

[0037] Example 2:

[0038] Please see Figures 3-5 This embodiment further illustrates the concept based on Embodiment 1:

[0039] The lifting assembly includes a threaded shaft 2 that is rotatably connected to the top of the fixed base 1 and driven by a motor. A lifting ring 21 is screwed onto the outer contour of the top of the threaded shaft 2. Connecting rods 22 are fixedly connected to the outer contours of both sides of the lifting ring 21. A guide rod 23 is fixedly connected to the end of the connecting rod 22 away from the lifting ring 21. Multiple sets of equally spaced ring gears 24 are fixedly connected to the lower half of the guide rod 23.

[0040] The follower assembly includes an adjusting roller 3 that is rotatably connected to the top of the positioning seat 12 and is traversed through and limited by the center of the adjusting roller 3 and slidably connected to the guide rod 23. A guide rail 31 is fixedly connected to the outer contour of the top of the adjusting roller 3. Two mirror-symmetrically distributed racks 32 are slidably connected to the upper surface of the guide rail 31. Positioning rods 33 are fixedly connected to the outer contours of both sides of the guide rail 31. The top of the positioning rod 33 is rotatably connected to a transmission wheel 34 through a pin, and the transmission wheel 34 meshes with and is connected to the rack 32. A transmission wheel 35 is meshed with and connected to the outer contour of the transmission wheel 34 near the guide rod 23, and the transmission wheel 35 also meshes with and is connected to the guide rod 23. The transmission wheel 35 does not contact the rack 32.

[0041] The follower assembly also includes a folding shaft 36 that passes through and is rotatably connected to the end of rack 32 away from the adjusting roller 3. Rack 37 is also rotatably connected to the outer contour of the folding shaft 36, and rack 37 is set with the same tooth shape as rack 32. The end of rack 37 away from rack 32 is passed through and rotatably connected to a fixing clip 38 that is snapped onto the tent frame to fix the device.

[0042] During installation, the equipment is placed on top of the tent and the threaded shaft 2 is rotated. At this time, the personnel hold the fixed seat 1 to prevent it from rotating. The rotation of the threaded shaft 2 causes the lifting ring 21 to tend to move synchronously. The movement tendency of the lifting ring 21 is further transmitted to the connecting rod 22 and the guide rod 23. Since the bottom end of the guide rod 23 is slidably connected to the inside of the adjusting roller 3, and the adjusting roller 3 is rotatably connected to the top of the positioning seat 12, the adjusting roller 3 and the guide rod 23 are limited by the positioning seat 12, the connecting rod 11, and the fixed seat 1 and cannot rotate synchronously with the threaded shaft 2. Furthermore, the rotation of the threaded shaft 2 causes the lifting ring 21, the connecting rod 22, and the guide rod 23 to start to rise and fall. As the guide rod 23 gradually extends out from the inside of the adjusting roller 3, the overall height of the equipment rises synchronously. The trapping component located above the lifting component rises synchronously to complete the adjustment of the light source height.

[0043] At the same time, as the guide rod 23 gradually extends out from inside the adjusting roller 3, the position and height of the adjusting roller 3 are kept constant due to the restriction of the positioning seat 12, the connecting rod 11, and the fixed seat 1. That is, at this time, there is a relative displacement between the guide rod 23 and the adjusting roller 3. At this time, the ring gear 24 on the outer contour of the guide rod 23 rises synchronously and drives the transmission wheel 35 and the transmission wheel 34 to rotate. The transmission wheel 34 further causes the rack 32 to start to extend outward along the setting direction of the guide rail 31 under the meshing action of its rack 32, and the whole equipment begins to expand.

[0044] It should be noted that for the large-span flat-top tents used in tent hospitals, a slight slope or inclination is set at the top to allow rainwater to flow along the top surface to the edge of the tent for drainage. As rack 32 extends outward, it squeezes and drives folding shaft 36, rack 37, and fixing clamp 38 to extend simultaneously. When rack 37 extends to the point where it contacts and disengages from guide rail 31, the support force of guide rail 31 on rack 37 disappears. At this time, rack 37, under the combined action of its own weight and the weight of fixing clamp 38, causes rack 37 to deflect at a certain angle along folding shaft 36. At this time, there is an angle between rack 32 and rack 37 to adapt to the slight curvature of the top of the large-span flat-top tent, thereby improving the stability of the equipment.

[0045] As rack 32 gradually extends, clamp 38 expands synchronously until it contacts the umbrella ribs around the top of the large-span flat-top tent. At this point, clamping clamp 38 onto the umbrella ribs of the tent completes the overall installation and fixing of the equipment.

[0046] It should be noted that during installation, adjusting the rotating adjusting roller 3 can freely adjust the orientation of the rack 32, thereby controlling the overall expansion direction of the equipment to meet the installation requirements of different types of tents; at the same time, the expansion degree of the two follower mechanisms is always synchronized. When one of the fixing clips 38 contacts and engages with the umbrella ribs first, the continued expansion of the follower mechanism will cause the equipment to move towards the center of the tent and position the equipment at the center of the tent top when the other fixing clip 38 engages with the umbrella ribs, thereby effectively optimizing the diffusion range of the light source to cover the top of the tent to the greatest extent.

[0047] On the other hand, once both fixing clips 38 are engaged with the umbrella ribs, the follow-up mechanism cannot continue to expand, thus locking itself in place. At this point, the threaded shaft 2 cannot rotate synchronously, fixing the height of the equipment. This means there is a chain relationship between the height of the equipment and the expansion length. The illumination height of the light source is determined based on the tent size during installation, ensuring that the equipment is always at the optimal illumination height and avoiding the problem of reduced light attraction effect due to excessive manual height adjustment.

[0048] Example 3:

[0049] Please see Figures 6-8 This embodiment further illustrates the concept based on Embodiment 2:

[0050] The spring-loaded mechanism includes a positioning plate 4 that is penetrated and fixedly connected to a guide rod 23. A spline shaft 41 is rotatably connected to the top of the positioning plate 4. A return spring 42, sleeved on the outer contour of the spline shaft 41, is fixedly connected to the top of the positioning plate 4. A transmission seat 43 is fixedly connected to the top of the spline shaft 41. A spiral track 44 is fixedly connected to the outer contours of both sides of the transmission seat 43. A transmission ring 45 is sleeved on the outer contour of the transmission seat 43. Positioning pins 46 are fixedly connected to the inner contours of both sides of the transmission ring 45 and are pulsatorically connected to the spiral track 44. A follower ring 47 is fixedly connected to the outer contour of the transmission ring 45 and is penetrated and fixedly connected to the guide rod 23. A limit ring 48 is fixedly connected to the top of the transmission ring 45. Limiting pins 49 are penetrated and fixedly connected to both sides of the outer contour of the limit ring 48.

[0051] The positioning plate 4 is equipped with a compressor driven by a trigger motor, and the spline shaft 41 is connected to the motor inside the positioning plate 4.

[0052] The blowing mechanism includes a top plate 5 fixedly connected to the top of the guide rod 23. A fixing ring 51 is fixedly connected to the outer contour of the lower surface of the top plate 5. A guide ring 52 is fixedly connected to the inner contour of the fixing ring 51 and is also fixedly connected to the lower surface of the top plate 5. An ultraviolet lamp 53 for mosquito attraction is fixedly connected to the center of the lower surface of the top plate 5.

[0053] The blowing mechanism also includes a closed seat 54 that is penetrated and fixedly connected to the outer contour of the guide rod 23 and is sleeved on the outer contour of the limiting ring 48. A limiting groove 55 is formed on the inner contour of the closed seat 54 and the limiting groove 55 corresponds to the position of the limiting pin 49.

[0054] The limiting groove 55 and the limiting pin 49 are interference-fitted, and the closed seat 54 and the limiting ring 48 are snapped together. The ratio of the opening length of the limiting groove 55 to the height of the transmission seat 43 is 1:2. The guide ring 52 is connected to the compressor inside the positioning plate 4 through an external conduit. The contact surfaces of the fixing ring 51 and the closed seat 54 are set with mutually cooperating inclined surfaces, and the ratio of the inclined surface length of the closed seat 54 to the inclined surface length of the fixing ring 51 is 2:1.

[0055] During installation, the entire trapping assembly rises synchronously with the guide rod 23. The rise of the positioning plate 4 activates the internal trigger motor, which in turn drives the entire trapping assembly. At this time, the motor drives the spline shaft 41 and the transmission seat 43 to rotate. The transmission seat 43 further drives the spiral track 44 to rotate synchronously. As the spiral track 44 rotates, it gradually squeezes the positioning pin 46, causing the positioning pin 46 and the transmission ring 45 to move synchronously. Since the transmission ring 45 is fixedly connected to the follower ring 47, and the follower ring 47 is fixedly connected to the guide rod 23, neither the follower ring 47 nor the transmission ring 45 can rotate. At this time, the compression of the positioning pin 46 by the spiral track 44 causes the positioning pin 46, the transmission ring 45, the follower ring 47, and the limiting ring 48 to contract downwards synchronously, and the deformation of the return spring 42 gradually increases.

[0056] As the spiral track 44 rotates further, when the positioning pin 46 is squeezed and moves down to its limit distance, the contact between the spiral track 44 and the positioning pin 46 disappears. At this time, the return spring 42 is also compressed to its limit. Since the pressure of the spiral track 44 on the positioning pin 46 disappears, the transmission ring 45 drives the positioning pin 46, the follower ring 47 and the limit ring 48 to bounce up quickly under the rebound action of the spiral track 44. At this time, the positioning pin 46 bounces back to its initial height and waits to re-contact with the next spiral track 44. Thus, with the continuous rotation of the spline shaft 41, the limit ring 48 slowly descends and quickly bounces up in a reciprocating cycle. The descending and bouncing height of the limit ring 48 is equal to the height setting of the transmission seat 43.

[0057] During this process, the limiting ring 48 slowly descends and then quickly springs up, causing the limiting pin 49 to move synchronously. Because the limiting pin 49 and the limiting groove 55 are interference-fitted, the closing seat 54 and the limiting ring 48 are engaged. That is, the movement of the limiting ring 48 is synchronously transmitted to the closing seat 54. When the closing seat 54 springs up synchronously and contacts the fixing ring 51, the inclined surfaces between the fixing ring 51 and the closing seat 54 fit together and are engaged by a snap-fit. Then, when the limiting ring 48 causes the limiting pin 49 to descend slowly, the engagement between the fixing ring 51 and the closing seat 54 causes the closing seat 54 to be limited by the fixing ring 51 and cannot descend with the limiting pin 49. That is, at this time, the limiting pin 49 slides in the limiting groove 55.

[0058] When the limiting pin 49 slides down to its limit distance in the limiting groove 55, the downward stroke of the limiting ring 48 is more than halfway. At this time, the pulling force of the limiting pin 49 on the closing seat 54 is greater than the locking force between the fixed ring 51 and the closing seat 54. The limiting ring 48 continues to descend and drives the limiting pin 49 and the closing seat 54 to move synchronously. In the subsequent rapid rebound process, the closing seat 54 also hits the fixed ring 51 and re-engages. The limiting pin 49 continues to move with the limiting ring 48 and slides upward to its limit position in the limiting groove 55. That is, the overall movement stroke of the closing seat 54 is half of that of the limiting ring 48.

[0059] At the same time, the compressor inside the positioning plate 4 works synchronously and continuously blows air vertically downward along the external duct to guide the airflow ring 52. The airflow ejected downward by the guide ring 52 contacts the inclined surface of the sealing seat 54 and flows inward in turbulence along the inclined surface of the sealing seat 54. At this time, the mosquitoes attracted by the ultraviolet lamp 53 and gathered near the ultraviolet lamp 53 are blown and pressed into the temporary storage space inside the sealing seat 54 and on the upper surface of the limiting ring 48 under the guidance and impact of the airflow. Due to the existence of the turbulence effect, under the combined effect of the turbulence and the attraction effect of the ultraviolet lamp 53, the mosquitoes are not easy to escape through the air curtain blown out by the guide ring 52, thus effectively overcoming the escape behavior of the mosquitoes.

[0060] Furthermore, the movement of the sealing seat 54 intermittently seals the ultraviolet lamp 53, while the movement of the limiting ring 48 completes the physical killing process of the captured mosquitoes. Since the movement stroke of the sealing seat 54 is half that of the limiting ring 48, the sealing seat 54 contacts the fixing ring 51 in advance and completes the sealing of the ultraviolet lamp 53 during the process of the limiting ring 48 popping up and hitting the lower surface of the top plate 5. Subsequently, the limiting ring 48 hits the top plate 5 to crush the mosquitoes between the sealing seat 54 and the limiting ring 48 to complete the killing work. Since the sealing seat 54 has completed the sealing effect in advance, the airflow generated when the limiting ring 48 pops up will not cause the mosquitoes to escape. Thus, the multiple attraction and coordination of the light, airflow and popping mechanism can fully improve the efficiency of capturing and killing mosquitoes.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
