Description

Technical Field

[0001] The invention relates to the technical field of mosquito killing, in particular to a light-attracting mosquito killing device used in a tent hospital. Background Art

[0002] Tent hospitals usually use tunnel tents or large-span flat-top tents. Tunnel tents are used to connect different cabin modules and serve as corridors, reception areas or other functional areas. Large-span flat-top tents are used as bed areas, treatment areas, operating areas, etc., providing more internal space. Among them, large-span flat-top tents are areas where patients are concentrated and are more susceptible to mosquito infestation.

[0003] After searching, the Chinese patent with publication number CN114342894B includes a box body, a first storage chamber located on the box body, and also includes: a foldable and expandable tent frame located in the first storage chamber, a tent assembly covering the tent frame, and the tent assembly can be folded or unfolded with the tent frame; an attraction hole is provided on the surface of the tent assembly, and when the tent assembly is unfolded, insects can enter the interior of the tent assembly through the attraction hole; during use, when insects are attracted to the vicinity of the tent assembly by the LED light, the fan is driven to rotate by the motor to generate an inward airflow at the attraction hole, guiding the insects to enter the tent assembly with the airflow, thereby greatly improving the efficiency of attracting insects and eliminating the need for staff to watch on site, thereby protecting against mosquito bites.

[0004] However, in the above-mentioned patent, a single tent is used for light-attracting and mosquito-killing. The installation process is cumbersome and the volume of the light-attracting tent also needs to be considered. If the volume is too small, it is difficult to achieve the expected mosquito-killing effect. If the volume is too large, it will consume excessive land area and lack practical significance. On the other hand, the above-mentioned patent lacks a means of killing mosquitoes after luring mosquitoes into the tent. In the case of long-term use, the number of mosquitoes in the tent gradually increases. Due to the phototaxis of mosquitoes, they will block the LED lamp to a large extent, thereby causing a decrease in the light-attracting effect. In addition, in the above-mentioned patent, a fan is used to form a negative pressure inside the tent assembly. The volume and power of the fan also need to be considered. If the volume and power are too small, it is difficult to achieve the expected suction effect. If the volume and power are too large, it will be accompanied by noise and high power consumption, which will also affect its suction effect. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] See also Figures 1 to 9 The present invention provides a technical solution: a light-attracting mosquito-killing device for a tent hospital, comprising a fixed seat 1 and a lifting assembly at the top thereof, a follower assembly rotatably connected to both sides of the fixed seat 1, and a trapping assembly arranged at the top of the lifting assembly, wherein both sides of the fixed seat 1 are fixedly connected with a connecting rod 11, and one end of the connecting rod 11 away from the fixed seat 1 is fixedly connected with a positioning seat 12;

[0033] The trapping assembly includes a blowing and pressing mechanism for completing the mosquito lamp luring and steps and a pop-up mechanism for physically killing captured mosquitoes. The blowing and pressing mechanism is arranged at the top of the lifting assembly and is fixedly connected to the lifting assembly, and the pop-up mechanism is arranged inside the blowing and pressing mechanism and is transmission-connected to the blowing and pressing mechanism.

[0034] This device achieves the light-attracting effect on mosquitoes through diffuse irradiation of an ultraviolet light source of a specific wavelength. When mosquitoes gather near the light source, they are guided and impacted by the airflow of the blowing and pressing mechanism, thereby achieving the capture of the mosquitoes. Furthermore, the physical killing process of the captured mosquitoes is completed by the rapid ejection of the pop-up mechanism.

[0035] It should be noted that the physical killing process of the pop-up mechanism is specifically achieved in the form of impact and crushing, and through the structural coordination of the pop-up mechanism, the light source is gradually closed before the impact, thereby effectively overcoming the escape behavior of mosquitoes to improve their killing effect; on the other hand, while the pop-up mechanism is working, its reciprocating opening and closing movement synchronously completes the wiping operation on the surface of the light source, thereby reducing the problem of mosquitoes adhering to the surface of the light source and causing obstruction, resulting in a decrease in the light attractant effect.

[0036] The lifting assembly and the follower assembly cooperate to complete the installation of the equipment. During the installation of the equipment, the lifting assembly and the follower assembly work synchronously, and the follower assembly expands synchronously so that the equipment can adapt to the size and curvature of the top of the tent to meet the fixing process of different types of tents. The lifting assembly works synchronously and controls the height of the light source to avoid being blocked by the tarpaulin to the greatest extent, thereby optimizing the light source's attraction effect on mosquitoes; the fixing seat 1, the connecting rod 11 and the positioning seat 12 have a positioning effect, positioning the equipment at the center of the top of the tent to further optimize the diffusion range of the light source.

[0037] Embodiment 2:

[0038] See also Figure 3-Figure 5 This embodiment further illustrates the following on the basis of the first embodiment:

[0039] The lifting assembly includes a threaded shaft 2 which is connected to the top of the fixed seat 1 for limited rotation and driven by a motor, a lifting ring 21 is screwed on the outer contour of the top of the threaded shaft 2, connecting rods 22 are fixedly connected to the outer contours on both sides of the lifting ring 21, and a guide rod 23 is penetrated and fixedly connected to the end of the connecting rod 22 away from the lifting ring 21, and a plurality of groups of ring gears 24 arranged at equal intervals are fixedly connected to the outer contour of the lower half of the guide rod 23.

[0040] The follower assembly includes an adjusting roller 3 that penetrates and is limitedly rotated to the top of the positioning seat 12, and the center of the adjusting roller 3 is penetrated 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, and two racks 32 distributed in a mirror-symmetrical manner are slidably connected to the upper surface of the guide rail 31. Positioning rods 33 are fixedly connected to the outer contours on both sides of the guide rail 31. The top of the positioning rod 33 is rotatably connected to a transmission wheel 24 through a pin shaft, and the transmission wheel 24 is meshed and transmission-connected with the rack 1 32. A transmission wheel 1 35 is meshed and transmission-connected on the outer contour of the transmission wheel 24 close to the guide rod 23, and the transmission wheel 1 35 is also meshed and transmission-connected with the guide rod 23, and there is no contact between the transmission wheel 1 35 and the rack 1 32.

[0041] The follower assembly also includes a folding shaft 36 that penetrates and is rotatably connected to the end of the rack 1 32 away from the adjusting roller 3. The outer contour of the folding shaft 36 is also rotatably connected to a rack 2 37, and the rack 2 37 is arranged in the same tooth shape as the rack 1 32. The end of the rack 2 37 away from the rack 1 32 is penetrated and rotatably connected to a fixing clip 38 that is clamped on the tent rib to fix the device.

[0042] When installing the equipment, place the equipment on the top of the tent and rotate the threaded shaft 2. At this time, the person holds the fixed seat 1 to prevent it from rotating. The rotation of the threaded shaft 2 makes the lifting ring 21 tend to move synchronously. The movement trend 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, that is, at this time, the adjusting roller 3 and the guide rod 23 are both limited by the positioning seat 12, the connecting rod 1 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, and 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 the inside of the adjusting roller 3, the height of the adjusting roller 3 is restricted by the positioning seat 12, the connecting rod 11 and the fixed seat 1 to ensure that it remains unchanged. That is, at this time, a relative displacement occurs 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 1 35 and the transmission wheel 2 34 to rotate. The transmission wheel 2 34 further causes the rack 1 32 to begin to extend outward along the setting direction of the guide rail 31 under the meshing action of its rack 1 32, and the entire equipment begins to expand.

[0044] It should be noted that, for the large-span flat-top tent used in the tent hospital, a slight slope or inclination will be set on the top to allow rainwater to flow along the top surface to the edge of the tent to complete the drainage work. When the rack 1 32 extends outward, it squeezes and drives the folding axis 36, the rack 2 37 and the fixing clamp 38 to extend synchronously. When the rack 2 37 is extended to the point where it is out of contact with the guide rail 31, the supporting force of the guide rail 31 on the rack 2 37 disappears. At this time, the rack 2 37 is deflected by a certain angle along the folding axis 36 under the combined action of its own gravity and the fixing clamp 38. At this time, there is an angle between the rack 1 32 and the rack 2 37, which adapts to the small arc setting of the top of the large-span flat-top tent, thereby improving the stability of the equipment.

[0045] As the rack 32 gradually extends, the fixing clip 38 expands synchronously until it contacts the ribs around the top of the large-span flat-top tent. At this time, the fixing clip 38 is clamped on the ribs of the tent to complete the installation and fixing of the entire device.

[0046] It should be noted that, during the installation process, the direction of the rack 32 can be freely adjusted by adjusting the rotating adjusting roller 3, thereby controlling the overall expansion direction of the device 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 first contacts and completes the engagement with the ribs, the continued expansion of the follower mechanism will cause the device to move toward the center of the tent and position the device at the center of the top of the tent when the other fixing clip 38 completes the engagement with the ribs, thereby effectively optimizing the diffusion range of the light source so that it covers the top of the tent to the greatest extent.

[0047] On the other hand, when the two fixing clips 38 are engaged with the umbrella ribs, the follower mechanism cannot continue to expand and is locked. At this time, the threaded shaft 2 cannot rotate synchronously, so that the height of the device is fixed, that is, there is a linkage relationship between the height of the device and the expansion length. The irradiation height of the light source is determined according to the size of the tent during installation, thereby ensuring that the device is always at the optimal irradiation height, and avoiding the problem of reduced light attraction effect due to excessive manual adjustment of the height.

[0048] Embodiment three:

[0049] See also Figure 6-Figure 8 This embodiment further illustrates the following on the basis of the second embodiment:

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

[0051] A compressor driven by a trigger-type motor is arranged inside the positioning plate 4 , and the spline shaft 41 is drivingly connected to the motor inside the positioning plate 4 .

[0052] The blowing mechanism comprises 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 the guide ring 52 is also fixedly connected to the lower surface of the top plate 5, and an ultraviolet lamp 53 for performing mosquito lamp luring work is fixedly connected at the center of the lower surface of the top plate 5;

[0053] The blowing mechanism also includes a closing seat 54 that penetrates and is fixedly connected to the outer contour of the guide rod 23, and the closing seat 54 is sleeved on the outer contour of the limiting ring 48. A limiting groove 55 is provided on the inner contour of the closing 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 fit, and the closing seat 54 and the limiting ring 48 are snap-fitted. The ratio of the opening length of the limiting groove 55 to the height of the transmission seat 43 is one to two. The guide ring 52 is connected to the compressor inside the positioning plate 4 through an external conduit. The contact surface of the fixing ring 51 and the closing seat 54 is arranged with mutually matching inclined snap buckles, and the ratio of the inclined length of the closing seat 54 to the inclined length of the fixing ring 51 is two to one.

[0055] During the installation process, the trapping assembly as a whole rises synchronously with the guide rod 23, wherein the rise of the positioning plate 4 causes the trigger motor inside it to start working and drive the trapping assembly as a whole to work; at this time, the motor drives the spline shaft 41 and the transmission seat 43 to start rotating, and the transmission seat 43 further drives the spiral track 44 to rotate synchronously, and along with the rotation of the spiral track 44, it gradually squeezes the positioning pin 46 so that the positioning pin 46 and the transmission ring 45 have a tendency 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, that is, the follower ring 47 and the transmission ring 45 cannot rotate, at this time, the squeezing 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 limit ring 48 to shrink downward synchronously and the deformation degree of the reset spring 42 gradually increases.

[0056] As the spiral track 44 rotates further, when the locating pin 46 is squeezed and moved down to the limit distance, the contact between the spiral track 44 and the locating pin 46 disappears. At this time, the return spring 42 is also compressed to the limit. Since the pressure of the spiral track 44 on the locating pin 46 disappears, the transmission ring 45 drives the locating pin 46, the follower ring 47 and the limit ring 48 to bounce up rapidly under the rebound action of the spiral track 44. At this time, the locating pin 46 rebounds to the initial height and waits to re-contact the next spiral track 44, thereby completing the reciprocating cycle of the limit ring 48 slowly descending and quickly bouncing up accompanied by the continuous rotation of the spline shaft 41, and the descending and bouncing heights of the limit ring 48 are equal to the height setting of the transmission seat 43.

[0057] During this process, the limit ring 48 slowly descends and quickly bounces up, which drives the limit pin 49 to move synchronously. Since the limit pin 49 and the limit groove 55 are interference fit, the closing seat 54 and the limit ring 48 are engaged, that is, the movement process of the limit ring 48 is synchronously transmitted to the closing seat 54. When the closing seat 54 bounces up synchronously and contacts the fixed ring 51, the inclined surfaces between the fixed ring 51 and the closing seat 54 fit each other and the fixed ring 51 and the closing seat 54 are engaged by snap fastening. Then, when the limit ring 48 drives the limit pin 49 to slowly descend, since the fixed ring 51 and the closing seat 54 are engaged, the closing seat 54 is limited by the fixed ring 51 and cannot descend with the limit pin 49. That is, at this time, the limit pin 49 slides in the limit groove 55.

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

[0059] At the same time, the compressor inside the positioning plate 4 works synchronously and realizes continuous blowing operation of the guide ring 52 vertically downward along the external duct. The airflow ejected downward by the guide ring 52 contacts the inclined surface of the closing seat 54 and flows inwardly along the inclined surface setting direction of the closing seat 54. At this time, the mosquitoes gathered near the ultraviolet lamp 53 due to the luring effect of the ultraviolet lamp 53 are blown and pressed into the temporary storage space inside the closing seat 54 and on the upper surface of the limit ring 48 under the guidance and impact of the airflow. Due to the existence of the turbulent effect, under the joint action of the turbulent effect and the attraction effect of the ultraviolet lamp 53, it is not easy for the mosquitoes to escape through the air curtain blown by the guide ring 52, thereby effectively overcoming the escape behavior of the mosquitoes.

[0060] Furthermore, the intermittent closure of the ultraviolet lamp 53 is achieved through the movement of the closing seat 54, and the movement of the limiting ring 48 completes the physical killing process of the captured mosquitoes. Since the movement stroke of the closing seat 54 is half of the limiting ring 48, that is, in the process of the limiting ring 48 bouncing up and hitting the lower surface of the top plate 5, the closing seat 54 contacts the fixing ring 51 in advance and completes the closure of the ultraviolet lamp 53, and then the limiting ring 48 hits the top plate 5 to crush the mosquitoes between the closing seat 54 and the limiting ring 48 to complete the killing work. Since the closing seat 54 has completed the sealing effect in advance, the airflow generated when the limiting ring 48 bounces up will not cause the mosquitoes to escape, thereby fully improving the efficiency of capturing and killing mosquitoes through the multiple luring coordination of light, airflow and the opening and closing of the pop-up mechanism.

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