Description

Technical Field

[0001] The utility model relates to the technical field of mosquito killing, and particularly relates to a mosquito killing device. Background Art

[0002] Most of the existing mosquito killing methods and devices kill mosquitoes by using the toxicity of chemical drugs. In the case of long-term use, the toxicity of chemical drugs may cause harm to the body of users, and chemical drugs may also cause pollution to the environment. Moreover, the efficiency of such mosquito killing methods and devices is relatively low. Long-term use of insecticides has made mosquitoes develop a certain degree of drug resistance, and the killing efficiency will be reduced.

[0003] Therefore, mosquito killing devices have emerged. The existing mosquito catching devices include a housing, a mosquito attracting light source, a mosquito catching fan, and a mosquito collecting box. By using the sensitivity of mosquitoes to the attracting light, mosquitoes are attracted near the mosquito catching fan. The mosquito catching fan sucks the mosquitoes into the mosquito collecting box, and the mosquitoes are dried to death in the mosquito collecting box. Since only the mosquito catching fan provides suction, the mosquito catching ability of the mosquito catching fan is limited, resulting in a poor killing effect. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a mosquito killing device to solve the problem of poor killing effect of the existing mosquito killing devices in the prior art.

[0005] To achieve the above purpose, the utility model provides a mosquito killing device, including: a blower; a pipe body, the pipe body has an air duct, the air duct has an inhalation end for inhaling mosquitoes, the blower is communicated with the air duct and provides negative pressure for the inhalation end, and the inner wall surface of the inhalation end is an inclined surface; a baffle, the baffle is arranged at the inhalation end, and an inhalation gap is formed between the edge of the baffle and the inclined surface of the inhalation end.

[0006] Further, along the flow direction of the air flow in the air duct, the inclined surface inclines towards the direction close to the central axis of the pipe body.

[0007] Further, the inner wall surface of the inhalation end has a conical structure, the conical structure has an inclined surface, and along the flow direction of the air flow in the air duct, the opening size of the conical structure gradually decreases.

[0008] Further, the pipe body also has a polytetrafluoroethylene coating, and the polytetrafluoroethylene coating is located on the surface of the inclined surface.

[0009] Further, a cross beam is arranged in the pipe body, the mosquito killing device further includes an adjusting structure, the baffle is connected with the pipe body through the adjusting structure, and the length of the adjusting structure is adjustable, so that the axial position of the baffle at the inhalation end is adjustable.

[0010] Further, the adjusting structure includes a plurality of sub-segments, and at least some of the sub-segments are telescopically sleeved together to adjust the length of the adjusting structure.

[0011] Further, the baffle has a through-hole that penetrates both sides of the baffle and communicates with the air duct.

[0012] Further, the through-hole is conical, and along the flow direction of the air flow in the air duct, the opening size of the cone gradually decreases.

[0013] Further, the pipe body also has a discharge end relative to the suction end, and the fan is located at the discharge end.

[0014] Further, the mosquito killing device further includes a storage member. The pipe body also has a discharge end relative to the suction end, and the storage member is connected and communicated with the discharge end.

[0015] Applying the technical solution of the present utility model, by setting the inner surface of the suction end of the pipe body as an inclined surface and cooperating with the setting of the baffle, the baffle blocks part of the opening of the suction end, so that an inhalation gap is formed between the baffle and the inclined surface. According to Bernoulli's principle, the smaller the cross-sectional size of the channel, the greater the wind speed, the lower the pressure, and the greater the suction force naturally. Therefore, the setting of the above baffle blocks part of the opening size, so that the air flow all passes through the inhalation gap, making the air flow velocity at the inhalation gap relatively large, thus greatly improving the suction force of the air flow on mosquitoes, and further ensuring that the mosquitoes at the suction end can be sucked into the air duct. At the same time, due to the setting of the inclined surface, the flow direction of the air flow entering the inhalation gap is fan-shaped, thus avoiding the situation where the area where mosquitoes can be inhaled is reduced due to the baffle blocking, and ensuring the range of air flow attraction. The above setting improves the suction force on the mosquitoes at the suction end on the one hand, enabling the mosquitoes to be sucked into the air duct, and on the other hand, does not affect the size of the area where mosquitoes can be sucked, and can also increase the size of the area where mosquitoes can be sucked, thereby realizing the reliable capture of mosquitoes and improving the killing effect.

[0022] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present invention in detail with reference to the drawings and in combination with the embodiments.

[0023] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0024] In the present invention, in the absence of contrary description, the orientation terms such as "upper, lower, top, bottom" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contours of the components themselves, but the above orientation terms do not limit the present invention.

[0025] In order to solve the problem that the mosquito killing device in the prior art has a poor killing effect, the present invention provides a mosquito killing device.

[0026] As Figures 1 to 3 shown, a mosquito killing device includes a fan 10, a pipe body 20 and a baffle 30. The pipe body 20 has an air duct, and the air duct has an inhalation end for inhaling mosquitoes. The fan 10 is communicated with the air duct and provides negative pressure for the inhalation end. The inner wall surface of the inhalation end is an inclined surface 21; the baffle 30 is arranged at the inhalation end, and an inhalation gap is formed between the edge of the baffle 30 and the inclined surface 21 of the inhalation end.

[0027] In this embodiment, the inner surface of the suction end of the tube body 20 is set as an inclined surface 21. Meanwhile, in cooperation with the setting of the baffle 30, the baffle 30 blocks part of the opening at the suction end, so that a suction gap is formed between the baffle 30 and the inclined surface 21. According to Bernoulli's principle, the smaller the cross-sectional size of the channel, the greater the wind speed, the lower the pressure, and the greater the suction force naturally. Therefore, due to the setting of the baffle 30 blocking part of the opening size, the air flow all passes through the suction gap, resulting in a relatively large air flow velocity at the suction gap, thereby greatly improving the suction force of the air flow on mosquitoes, and further ensuring that the mosquitoes at the suction end can be sucked into the air duct. At the same time, due to the setting of the inclined surface 21, the flow direction of the air flow entering the suction gap is fan-shaped, thus avoiding the situation where the area where mosquitoes can be sucked is reduced due to the blockage of the baffle 30 and ensuring the range of air flow attraction. The above setting, on the one hand, improves the suction force on the mosquitoes at the suction end, enabling the mosquitoes to be sucked into the air duct, on the other hand, does not affect the size of the area where mosquitoes can be sucked, and can also increase the size of the area where mosquitoes can be sucked, thereby achieving reliable capture of mosquitoes and improving the killing effect.

[0028] As Figure 2 and Figure 3 shown, in this embodiment, along the flow direction of the air flow in the air duct, the inclined surface 21 inclines towards the direction close to the central axis of the tube body 20. In this way, for the inlet end of the suction gap, the formed air flow range is relatively large, presenting a relatively large approximate fan shape, thereby ensuring a relatively large area where mosquitoes can be sucked and ensuring the capture effect. Of course, the inclined surface 21 can also be set to incline towards the direction away from the central axis of the tube body 20. At this time, the air flow velocity is relatively fast and the suction force is greater, but it will have a certain impact on the area where mosquitoes can be sucked.

[0029] Preferably, the inner wall surface of the suction end of this embodiment has a conical structure, and the side surface of the conical structure is the above-mentioned inclined surface 21. And along the flow direction of the air flow in the air duct, the opening size of the conical structure gradually decreases, that is, the distance between the opposite inclined surfaces 21 on the conical structure gradually decreases. According to Figure 2The direction in [it] is that the opening size of the conical structure gradually decreases from top to bottom. The conical structure in this embodiment adopts a pyramid structure. The pyramid structure has four side faces, thus forming four inclined planes 21. Correspondingly, the baffle 30 is arranged as a rectangular plate, and its shape matches the cross-sectional shape of the pyramid structure. In this way, the four side edges of the rectangular plate can respectively cooperate with the four inclined planes 21 to form four suction gaps. The four suction gaps cover the range of 360 degrees in the circumferential direction of the pipe body 20, thereby ensuring the suction force in the entire circumferential direction and ensuring that mosquitoes in all directions can be sucked into the air duct by the airflow. Further preferably, the distances between the four side edges of the rectangular plate and the four inclined planes 21 are all equal, so as to ensure the balance of the suction force within the circumferential range and avoid the situation that the suction force at some positions is weakened due to the uneven size of the suction gaps. Of course, the conical structure can also adopt other structural forms such as a cone. Correspondingly, the shape of the baffle 30 and the specific cooperation relationship with the conical structure can also be adjusted as needed.

[0030] The pipe body 20 in this embodiment includes multiple segments, and the segments are axially connected in sequence to form the entire pipe body 20. Among them, the segment at the suction end has the aforementioned conical structure, while other segments can be arranged as cylindrical structures. Considering the shape difference between the conical structure and the cylindrical structure, a sealing plate can be added at the connection between the segment of the conical structure and the segment of the cylindrical structure to block the part that cannot be completely docked, thereby ensuring the overall sealing effect of the pipe body 20 and further ensuring the suction force at the suction end. Of course, the pipe body 20 can also adopt a shape that is entirely cylindrical or conical, etc., and it can adopt a split structure or an integral structure.

[0031] The pipe body 20 in this embodiment also has a polytetrafluoroethylene coating, and the polytetrafluoroethylene coating is located on the surface of the inclined plane 21. The reason for setting the polytetrafluoroethylene coating is that considering that mosquitoes are easily hit on the inclined plane 21 during the inhalation process, resulting in a large number of mosquitoes adhering or sticking to the inclined plane 21, which in turn affects the subsequent capture of mosquitoes. Based on the above situation, by setting the polytetrafluoroethylene coating, the characteristics of the coating material can be used to reduce the situation of mosquitoes adhering to the inclined plane 21, thereby avoiding the blockage of the suction gap and other situations, ensuring the reliability of long-term use, and reducing the number of manual inspections.

[0032] Such as Figure 2As shown, in this embodiment, a cross beam 22 is provided inside the pipe body 20. The cross beam 22 can be perpendicular to the axis of the pipe body 20. The mosquito killing device further includes an adjusting structure 40. One end of the adjusting structure 40 is connected to the cross beam 22, and the other end is connected to the baffle 30, so that the baffle 30 is connected to the pipe body 20 through the adjusting structure 40, realizing the installation and fixation of the baffle 30. In this embodiment, the adjusting structure 40 is arranged on the surface with a larger area of the baffle 30, rather than on the side edge. In this way, the position of the adjusting structure 40 will not affect the suction gap, thus ensuring the suction effect of the suction gap. At the same time, the length of the adjusting structure 40 in this embodiment is adjustable. In this way, by adjusting the length of the adjusting structure 40, the axial position of the baffle 30 at the suction end can be adjusted, thus realizing the adjustment of the position of the baffle 30, realizing the adjustment of the relative position between the baffle 30 and the inclined surface 21, and also realizing the adjustment of the size, the size and position of the mosquito-sucking area of the suction gap, so that the mosquito killing device can adjust its own suction force according to the usage scenario, and further improve the adaptability to different environments.

[0033] The adjusting structure 40 in this embodiment includes a plurality of sub-segments, and at least some of the sub-segments are telescopically sleeved together to adjust the length of the adjusting structure 40. That is to say, the adjusting structure 40 in this embodiment adopts the form of a telescopic structure. Taking the example of having two sub-segments, the diameter of one sub-segment is larger than that of the other sub-segment, so that the sub-segment with a smaller diameter can extend into the sub-segment with a larger diameter. At this time, a plurality of positioning holes can be provided on the two sub-segments, and by using the docking cooperation between different positioning holes on the two sub-segments, and using bolts and other components to pass through different positioning holes, the adjustment of the position between the two sub-segments can be realized; or directly using the frictional force of the interference fit between the two sub-segments and other methods to realize the adjustment of the position between the two sub-segments, thus realizing the adjustment of the length of the adjusting structure 40, and also realizing the adjustment of the position of the baffle 30. Of course, in addition to adopting the form of a telescopic structure, the adjusting structure 40 can also adopt other structural forms, such as using two articulated connecting rods, and setting a locking structure at the articulated part to realize the adjustment of the angle formed between the two connecting rods, so as to realize the adjustment of the distance between the two ends, etc., as long as the distance between the two ends of the adjusting structure 40 can be adjusted, and then the position of the baffle 30 can be adjusted.

[0034] The baffle 30 in this embodiment has through holes, and the through holes penetrate both sides of the baffle 30 and are communicated with the air duct. The number of through holes can be set as required, and one or more can be set. In this embodiment, it is preferably provided with a plurality of through holes, and the through holes are arranged in an array along the surface of the baffle 30. In this way, through the setting of the through holes, the mosquitoes in the area blocked by the baffle 30 can also be sucked into the air duct under the action of the air flow at the through holes, thus further increasing the size of the mosquito-sucking area and improving the killing effect.

[0035] The through holes in this embodiment are conical, and along the direction of the airflow in the air duct, the size of the conical opening gradually decreases. That is to say, the large opening end of the cone faces outward from the air duct, and the small opening end of the cone faces inward into the air duct. According to Figure 2 the direction is that the large opening end is upward and the small opening end is downward. In this way, on the one hand, mosquitoes can still enter the through hole from the large opening end under the action of the airflow, and then pass through the baffle 30 from the small opening end and be sucked into the air duct, ensuring that mosquitoes can be sucked into the air duct. On the other hand, it can prevent mosquitoes from escaping from the air duct through the through hole, achieving the effect of preventing mosquito escape and ensuring the reliability of capture.

[0036] Preferably, the through holes in this embodiment are trapezoidal in reverse, and of course, in addition to being set as trapezoidal in reverse, other shapes such as frustum of a cone in reverse can also be used.

[0037] In this embodiment, the pipe body 20 also has a discharge end relative to the suction end, that is, the two ends of the pipe body 20 are the suction end and the discharge end respectively. The suction end is used to suck in mosquitoes, and the discharge end is used to discharge mosquitoes into subsequent components. The fan 10 is located at the discharge end, and the fan 10 provides power for the flow of the airflow to ensure that a negative pressure is formed at the suction end, and setting the fan 10 at the discharge end can avoid the influence of the fan 10 on the suction end.

[0038] As Figure 1 and Figure 2 shown, in this embodiment, the mosquito killing device further includes a storage member 50. The storage member 50 can be components such as a storage box. The storage member 50 is located at the discharge end of the pipe body 20 and is connected and communicated with the discharge end. Thus, mosquitoes enter the pipe body 20 from the suction end, and then are discharged from the discharge end into the storage member 50 for storage or subsequent disinfection and other treatments in the storage member 50.
