[0001] The utility model relates to the technical field of mosquito killing, and in particular, 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 environmental pollution. Moreover, the efficiency of such mosquito killing methods and devices is relatively low. Long-term use of insecticides has made mosquitoes develop a certain 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 to the vicinity of the mosquito catching fan, and the mosquito catching fan sucks the mosquitoes into the mosquito collecting box, where the mosquitoes are dried to death. This kind of device kills mosquitoes only by attracting them with light, and the efficiency is relatively low. And some solutions adopt the method of carbon dioxide trapping, which includes a housing, a carbon dioxide storage tank, and an electric grid. The carbon dioxide source is a one-time canned gas source. After the gas source is exhausted, a new gas source needs to be replaced in time. The efficiency is low, the cost is high, and it consumes manpower, and the killing effect is poor. Summary of the Utility Model

[0024] In order to solve the problem of poor killing effect of the mosquito killing device in the prior art, the present utility model provides a mosquito killing device.

[0025] As Figure 1 and Figure 2 shown, a mosquito killing device includes a housing 10, a light source 20, a carbon dioxide generator 30, a pipe body 40, a fan 50 and a mosquito storage member 60. The housing 10 has a mosquito attracting chamber 11, and the mosquito attracting chamber 11 has mosquito attracting holes 12; the light source 20 is arranged in the mosquito attracting chamber 11; the carbon dioxide generator 30 is arranged in the housing 10 and can introduce carbon dioxide into the mosquito attracting chamber 11; the pipe body 40 is arranged in the housing 10, and the pipe body 40 has an air duct communicating with the mosquito attracting chamber 11; the fan 50 is communicated with the pipe body 40 and provides suction for attracting mosquitoes to the pipe body 40; the mosquito storage member 60 is arranged in the housing 10 and communicated with the pipe body 40, and the mosquitoes sucked by the negative pressure of the pipe body 40 are transported into the mosquito storage member 60.

[0026] In this embodiment, a light source 20 and a carbon dioxide generator 30 are provided. The light source 20 can emit specific light rays to attract mosquitoes, and the carbon dioxide generator 30 can emit carbon dioxide to also attract mosquitoes. In this way, the light source 20 and the carbon dioxide generator 30 cooperate to achieve the effect of attracting mosquitoes. Moreover, the light source 20 can continuously emit light by itself, and the carbon dioxide generator 30 can continuously generate carbon dioxide by itself. As a result, both the light source 20 and the carbon dioxide generator 30 are components that can be used for a long time. When in use, on the one hand, it can enhance the attracting effect on mosquitoes, thereby improving the killing effect. On the other hand, the light source 20 and the carbon dioxide generator 30 do not require frequent maintenance and can be used for a long time, thus improving the convenience of use, reducing costs, and also being able to improve the killing effect. At the same time, the setting of the pipe body 40 and the fan 50 can suck the mosquitoes attracted by the light source 20 and the carbon dioxide generator 30 into the pipe body 40 through negative pressure and transport them to the mosquito storage member 60 through the pipe body 40, so as to carry out the treatment of mosquitoes. The above setting method, on the one hand, improves the attracting effect on mosquitoes from the perspective of attracting mosquitoes, and on the other hand, improves the treatment effect on mosquitoes from the perspective of mosquito treatment. At the same time, the number of times the entire device needs to be maintained is greatly reduced, thereby improving efficiency, reducing costs, saving manpower and material resources, and being beneficial to improving the killing effect.

[0027] In this embodiment, the pipe body 40 has an inhalation end, and the inhalation end is communicated with the mosquito attracting chamber 11. The light source 20 and the carbon dioxide generator 30 are both arranged at the inhalation end, and the light source 20 faces the inhalation end directly, so that the mosquitoes attracted into the mosquito attracting chamber 11 can be sucked into the pipe body 40 in time to ensure the capture effect.

[0028] The device of this embodiment is arranged longitudinally as a whole. Therefore, the axis of the pipe body 40 is arranged longitudinally. The top end of the pipe body 40 serves as the inhalation end. Both the light source 20 and the carbon dioxide generator 30 are located above the inhalation end, and the air outlets of the light source 20 and the carbon dioxide generator 30 are both arranged downward, so that the attracted mosquitoes fly into the inhalation range of the inhalation end to ensure the reliability of capturing mosquitoes. The light source 20 and the carbon dioxide generator 30 can be arranged at intervals in the longitudinal direction, which is convenient for layout.

[0029] The housing 10 of this embodiment is generally cylindrical. The cavity inside the housing 10 is divided into three regions from top to bottom. Among them, the upper region is the installation region for the light source 20 and the carbon dioxide generator 30, that is, the light source 20 and the carbon dioxide generator 30 are installed in the upper part of the housing 10. The lower region is the installation region for the mosquito storage member 60, that is, the mosquito storage member 60 is installed in the lower part of the housing 10. And the middle region between the upper region and the lower region is the region for attracting mosquitoes. The middle region is the interval between the light source 20 and the carbon dioxide generator 30 and the suction end, that is, the mosquito attracting chamber 11. Thus, the light source 20 and the carbon dioxide generator 30 are arranged at intervals relative to the suction end. Mosquito attracting holes 12 are provided at the side wall of the middle region, so that mosquitoes can enter the mosquito attracting chamber 11 through the mosquito attracting holes 12, achieving the attraction of mosquitoes and ensuring that the mosquitoes entering the mosquito attracting chamber 11 are sucked into the tube body 40 by the negative pressure of the suction end. Of course, the specific structural form of the housing 10 is not limited to the above manner of this embodiment, and it can be adjusted accordingly as needed, as long as it can achieve the installation of components and the entry of mosquitoes.

[0030] The light source 20 of this embodiment uses an ultraviolet lamp. Of course, other types of light sources 20 can also be used, as long as the effect of attracting mosquitoes can be achieved. The carbon dioxide generator 30 uses a device that can generate carbon dioxide by itself and continuously, so as to achieve the self-production and self-use of carbon dioxide, without the need to frequently add or replace carbon dioxide, improving the convenience of use.

[0031] In this embodiment, the mosquito killing device further includes a grating sensor. The grating sensor is arranged outside the tube body 40, and counting holes are provided on the side of the tube body 40. In this way, the grating sensor can detect the number of mosquitoes in the tube body 40 through the counting holes, thus achieving the effect of counting the killed mosquitoes.

[0032] In order to make the counting accurate, in this embodiment, the grating sensor is arranged outside the position with the smallest internal opening size of the tube body 40, that is, at the narrowest part of the air duct. And the air duct is set as a rectangle. The grating sensor is installed outside the air duct, and counting holes are provided at the position of the housing 10 corresponding to the grating sensor and at the position on the other side opposite to this position, so as to ensure the counting function of the grating. Since the volume of mosquitoes is small, in order to ensure the counting accuracy, the grating slit spacing formed by the counting holes in this embodiment is 1 mm.

[0033] The mosquito killing device of this embodiment can also be interconnected and communicate with external devices. Specifically, the functional interaction can be enhanced through components such as grating sensors. For example, the mosquito state of the environment where the mosquito killing device is located at a certain time can be judged by collecting the number of mosquitoes within a certain period of time. Another example is that multiple mosquito killing devices can be set up in different environments to count the number of mosquitoes at the same time period and different locations, so as to monitor the environment and achieve the function of feedback.

[0034] In this embodiment, the mosquito killing device further includes a human body sensor and a light sensor. The human body sensor is electrically connected to both the light source 20 and the carbon dioxide generator 30. The human body sensor can detect the human body state around the mosquito killing device and control the turning on and off of the light source 20 and the carbon dioxide generator 30 according to the human body state. The human body sensor can sense human activity information through infrared rays and pyroelectric principle and be linked with the light source 20 and the carbon dioxide generator 30, so as to turn off the light source 20 and the carbon dioxide generator 30 when a person approaches to avoid harm to the human body. The light sensor is electrically connected to both the light source 20 and the carbon dioxide generator 30. The light sensor can detect the light state around the mosquito killing device and control the turning on and off of the light source 20 and the carbon dioxide generator 30 according to the light state. Since the effect of attracting mosquitoes by light during the day is poor, a light sensor is set to turn off the light source 20 during the day and only attract mosquitoes by releasing carbon dioxide, and automatically turn on the light source 20 at night for attracting, which can ensure the attracting effect and reduce the power consumption at the same time. Of course, either the human body sensor or the light sensor can also be selectively set according to needs.

[0035] Such as Figure 2As shown in the figure, in this embodiment, the inner wall surface of the suction end is set as an inclined surface. The mosquito killing device further includes a baffle 70. The baffle 70 is arranged at the suction end and blocks part of the opening of the suction end. An inhalation gap is formed between the edge of the baffle 70 and the inclined surface. In this way, through the setting of the inclined surface and in cooperation with the baffle 70, the baffle 70 blocks part of the opening of the suction end, so that an inhalation gap is formed between the baffle 70 and the inclined surface. According to Bernoulli's principle, the smaller the cross-sectional area of the channel, the greater the wind speed, the lower the pressure, and the greater the suction force naturally. Therefore, the setting of the baffle 70 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 blockage of the baffle 70 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 realizing the reliable capture of mosquitoes and improving the killing effect.

[0036] In this embodiment, along the flow direction of the air flow in the air duct, the inclined surface is inclined towards the direction close to the central axis of the pipe body 40. In this way, for the inlet end of the inhalation gap, the formed air flow range is relatively large, presenting a relatively large approximate fan-shaped shape, thus ensuring a relatively large area where mosquitoes can be inhaled and ensuring the capture effect. Of course, the inclined surface can also be set to be inclined away from the central axis of the pipe body 40. 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 inhaled.

[0037] Preferably, the inner wall surface of the suction end in this embodiment has a conical structure. The side surface of the conical structure is the above-mentioned inclined surface, 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 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. Correspondingly, the baffle 70 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 to form four suction gaps. The four suction gaps cover a range of 360 degrees in the circumferential direction of the pipe body 40, 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 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 uneven sizes 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 70 and the specific cooperation relationship with the conical structure can also be adjusted according to needs.

[0038] The pipe body 40 in this embodiment can include multiple segments, and the segments are axially connected in sequence to form the entire pipe body 40. Among them, the segment at the suction end has the aforementioned conical structure, while other segments can be arranged as a cylindrical structure or a square tube structure. 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 40 and further ensuring the suction force at the suction end. Of course, the pipe body 40 can also adopt a shape that is entirely cylindrical or conical, etc., and it can adopt a split structure or an integral structure.

[0039] The pipe body 40 in this embodiment also has a polytetrafluoroethylene coating, and the polytetrafluoroethylene coating is located on the surface of the inclined plane. The reason for setting the polytetrafluoroethylene coating is that when mosquitoes are sucked in, they are likely to hit the inclined plane, resulting in a large number of mosquitoes adhering or sticking to the inclined plane, 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, thereby avoiding situations such as blockage of the suction gap, ensuring the reliability of long-term use, and reducing the number of manual inspections.

[0040] In this embodiment, a cross beam 41 is arranged inside the pipe body 40. The cross beam 41 can be perpendicular to the axis of the pipe body 40. The mosquito killing device further includes an adjusting structure 80. One end of the adjusting structure 80 is connected to the cross beam 41, and the other end is connected to the baffle 70, so that the baffle 70 is connected to the cross beam 41 through the adjusting structure 80, realizing the installation and fixation of the baffle 70. In this embodiment, the adjusting structure 80 is arranged on the surface of the baffle 70 with a larger area, rather than on the side edge. In this way, the position of the adjusting structure 80 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 80 in this embodiment can be adjusted. In this way, by adjusting the length of the adjusting structure 80, the axial position of the baffle 70 at the suction end can be adjusted, thereby realizing the adjustment of the position of the baffle 70, realizing the adjustment of the relative position between the baffle 70 and the inclined plane, 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 according to the usage scenario, and further improve the adaptability to different environments.

[0041] The adjusting structure 80 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 80. That is to say, the adjusting structure 80 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 arranged on the two sub-segments, and by using the docking cooperation between different positioning holes on the two sub-segments, and using components such as bolts to pass through different positioning holes, the position adjustment 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 position adjustment between the two sub-segments, thereby realizing the adjustment of the length of the adjusting structure 80, and also realizing the adjustment of the position of the baffle 70. Of course, in addition to adopting the form of a telescopic structure, the adjusting structure 80 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 it can realize the adjustment of the distance between the two ends of the adjusting structure 80, and further realize the adjustment of the position of the baffle 70.

[0042] The baffle 70 in this embodiment has through holes, and the through holes penetrate through both sides of the baffle 70 and are communicated with the air duct. The number of through holes can be set according to needs, 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 70. In this way, through the setting of the through holes, the mosquitoes in the area blocked by the baffle 70 can also be sucked into the air duct under the action of the air flow at the through holes, thereby further increasing the size of the mosquito-sucking area and improving the killing effect.

[0043] The through hole in this embodiment is conical, and along the flow direction of the air flow in the air duct, the size of the opening of the cone gradually decreases. That is to say, the large opening end of the cone faces outside the air duct, and the small opening end of the cone faces inside 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 air flow, and then pass through the baffle 70 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 through hole of the air duct, achieving the effect of preventing mosquito escape and ensuring the reliability of capture.

[0044] Preferably, the through hole in this embodiment is in the shape of an inverted trapezoid. Of course, in addition to being set as an inverted trapezoid, other shapes such as an inverted frustum of a cone can also be used.

[0045] It should be noted that the multiple in the above embodiments refers to at least two.

[0047] 1. Solve the problem that the mosquito killing device in the prior art has a poor killing effect;

[0048] 2. On the one hand, improve the attraction effect on mosquitoes from the perspective of attracting mosquitoes, and on the other hand, improve the treatment effect on mosquitoes from the perspective of mosquito treatment;
