Description

Technical Field

[0001] This utility model relates to the field of insect killer technology, and in particular to an insect killer. Background Technology

[0002] Insect killers, which rely on light or attractants in conjunction with adhesive tape or a high-voltage electric grid to kill mosquitoes, are gradually gaining attention. Existing common insect killers fall into two categories: one uses adhesive tape and a UV lamp, taking advantage of mosquitoes' phototaxis to stick them to the tape; the other uses a UV lamp, a fan, and an electric grid. The UV lamp attracts mosquitoes, while the fan creates negative pressure to draw them into the killer, where they are then caught and killed by the electric grid.

[0003] In the process of realizing this utility model, the inventors of this utility model discovered that: currently, insect killers that combine adhesive tape and ultraviolet lamps are limited by the limited attraction of ultraviolet lamps to mosquitoes, and some mosquitoes fail to land on the adhesive tape after passing by the ultraviolet lamp and escape. In addition, the airflow in the surrounding environment also affects the trapping effect of the insect killer. In insect killers that combine ultraviolet lamps, fans and electric grids, the noise from the electric grid killing mosquitoes is too loud, which affects the trapping effect. Utility Model Content

[0004] This utility model provides an insect killer, which mainly solves the technical problem that the existing insect killers that use adhesive tape and ultraviolet lamps are not ideal in killing due to the influence of airflow, and the electric insect killers are too noisy, which affects the killing effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an insect killer, including a main body, a fan and adhesive tape. The main body is provided with a receiving cavity, an air inlet and an air outlet. The air inlet and the air outlet are both connected to the receiving cavity.

[0010] Optionally, the air inlet is inclined toward the fixing plate, and a first gap is left between the air inlet and the fixing plate.

[0011] Optionally, the fixing plate is provided with a first mating part, and the main body is provided with a second mating part, wherein the first mating part and the second mating part are inserted or magnetically connected.

[0012] Optionally, the insect killer includes a light bead, the main body is provided with a light-transmitting hole, the light-transmitting hole is connected to the receiving cavity, the light bead is housed in the receiving cavity, and the light from the light bead can be projected to the external environment through the light-transmitting hole.

[0013] Optionally, the LED beads include blue LED beads and ultraviolet LED beads.

[0014] Optionally, the insect killer includes a circuit board and a plug, the circuit board being housed in the receiving cavity, the plug being disposed in the main body, and the circuit board being electrically connected to the plug and the fan respectively.

[0019] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0021] This application provides an insecticide 100; please refer to [link / reference]. Figure 1 and Figure 2 The insect killer includes a main body 1, a fan 2, and adhesive tape 3. The main body 1 has a receiving cavity 11, an air inlet 12, and an air outlet 13. Both the air inlet 12 and the air outlet 13 are connected to the receiving cavity 11. The fan 2 is placed in the receiving cavity 11 and can form an air duct with the air outlet 13 and the air inlet 12 to accelerate the airflow in the receiving cavity 11. The adhesive tape 3 is placed outside the main body 1 and can kill mosquitoes in a natural state. The adhesive tape 3 is placed adjacent to the air inlet 12. The adhesive tape 3 installed at the air vent 12 allows the adhesive tape 3 to be located in the airflow path of the aforementioned air duct, so that mosquitoes can be carried to the adhesive tape 3 by the airflow after entering the air duct, thereby increasing the probability of killing mosquitoes near the adhesive tape 3. Moreover, this method of increasing the killing probability of the adhesive tape 3 by relying on the air duct is not affected by airflow compared to the insect killer 100 that simply relies on the ultraviolet lamp in conjunction with the adhesive tape 3. Compared with the electric shock insect killer 100, it is quieter and avoids disturbing the user.

[0022] Understandably, the arrangement of the air inlet 12 allows the forces around the air duct to act fully on the adhesive tape 3, so that when a negative pressure is formed in the area around the air inlet 12, the surrounding air can push the mosquitoes to the adhesive tape 3, increasing the probability that the adhesive tape 3 will stick to the mosquitoes.

[0023] Furthermore, the aforementioned fan 2 is preferably a turbine-structured fan 2 to ensure that the fan 2 has sufficient suction.

[0024] In some embodiments, please refer to Figure 3 An air inlet 12 is located at one end of the main body 1, and an air outlet 13 is located at the other end of the main body 1, forming an air duct that runs through the main body 1. This straight-through air duct generates a higher wind speed than a curved and coiled air duct under the same power of the fan 2, resulting in better mosquito killing efficiency. Furthermore, the air inlet 12 is tilted towards the adhesive paper 3, so that the flow direction of the air duct can be biased towards the adhesive paper 3. According to Bernoulli's principle, the increased flow velocity between the air inlet 12 and the adhesive paper leads to a decrease in static pressure at that location, forming a negative pressure zone relative to the surrounding environment, thereby increasing the suction force at that location and improving the probability of mosquito killing.

[0025] It is understandable that the adhesive tape 3 is externally placed on the main body 1, and the connection between the adhesive tape 3 and the main body 1 includes, but is not limited to, adhesive bonding, snap-fitting, and fixing by relying on the back plate.

[0026] It should be noted that when the adhesive tape 3 is placed outside the main body 1, the adhesive tape 3 needs to maintain sufficient structural strength to prevent unexpected large-scale shaking or displacement of the adhesive tape 3 under the suction of the air duct formed by the fan 2, air inlet and air outlet, which would affect the killing effect of the insect killer 100. For example, the adhesive tape 3 can be made of thick cardboard.

[0027] In some preferred embodiments, a fixation method relying on a back plate is used; for details, please refer to [link / reference]. Figure 1 and Figure 4 The insect killer 100 includes a fixing plate 4, which is disposed on the outer side wall of the main body 1. The adhesive tape 3 is attached to the fixing plate 4. The presence of the fixing plate 4 increases the fixing strength of the adhesive tape 3 on the outside of the main body 1, which can reduce the shaking of the adhesive tape 3 during the use of the insect killer 100. In addition, the presence of the fixing plate 4 can also guide the user to insert or snap the tape into the direction and angle, which improves the convenience of the user to replace the adhesive tape 3.

[0028] Furthermore, the fixing plate 4 is provided with a guide groove 41, which is connected to the air inlet 12. The opening of the guide groove 41 faces the main body 1. Specifically, the fixing plate 4 is bent towards the adhesive tape 3 to form the guide groove 41, so that the opening of the guide groove 41 faces the main body 1. The presence of the guide groove 41 allows the fan 2 to guide the external airflow when it cooperates with the air inlet and air outlet to form an air duct that runs through the main body 1. This creates an external air duct that cooperates with the air duct structure, allowing mosquitoes near the adhesive tape 3 to be carried away by the external air duct in cooperation with the air duct, thus increasing the killing probability of the insect killer 100.

[0029] In some embodiments, please refer to Figure 3 The air inlet 12 is inclined towards the fixing plate 4, and a first gap 121 is left between the air inlet 12 and the fixing plate 4. The existence of the first gap 121 allows the external air duct to form a narrow tube effect at the air inlet 12 (when airflow passes through narrow terrain on the ground, it is similar to the flow of liquid in a pipe, the flow velocity will also increase, and the density will also increase due to the compressibility of gas). The increase in flow velocity will increase the suction force at this point, thereby improving the capture ability of mosquitoes falling in the vicinity. The adhesive tape 3 is attached to the side of the fixing plate 4 near the main body 1 to ensure the effectiveness of the tape and the air duct.

[0030] In some embodiments, the main body 1 further includes a screen 14, which is detachably disposed at the air inlet 12 and the air outlet 13 of the main body 1 to prevent mosquitoes or other foreign objects from entering the air duct through the air inlet 12 and affecting the operation of the fan 2.

[0031] Understandably, the adhesive tape 3 is attached to the fixing plate 4 in ways including but not limited to: gluing, snap-fitting, etc.

[0032] For example, in some embodiments, the adhesive tape 3 is used in a snap-fit ​​manner; for details, please refer to [link to relevant documentation]. Figure 4 The fixing plate 4 has two locking parts 42 extending from the two ends of the wall of the guide groove 41 facing the groove opening. The locking parts 42 are parallel to the bottom of the guide groove 41. When the user needs to replace the adhesive tape 3, he / she only needs to roll up the adhesive tape 3 and push it into the guide groove 41 from the end away from the main body 1 along the direction of the guide groove 41. After the adhesive tape 3 is completely pushed into the guide groove 41, the two sides of the adhesive tape 3 can smoothly abut against the locking parts 42. When the adhesive tape 3 is bent by external force, due to the existence of its internal stress, the adhesive tape 3 will generate an elastic restoring force to resist bending deformation and restore flatness. However, since the two sides of the adhesive tape 3 are limited by the locking parts 42, the elastic restoring force of the adhesive tape 3 can only show the tendency to restore flatness and stick to the surface of the fixing plate 4. Under the action of this elastic restoring force, the adhesive tape 3 can be firmly limited in the guide groove 41.

[0033] It is understandable that the connection methods between the fixing plate 4 and the main body 1 include, but are not limited to: detachable connection methods such as screw connection, snap connection, magnetic attraction, or permanent connection methods such as one-piece molding.

[0034] For example, in some embodiments, please refer to Figure 4 The fixing plate 4 and the main body 1 are detachably connected. The fixing plate 4 is provided with a first mating part 43, and the main body 1 is provided with a second mating part 15. The first mating part 43 and the second mating part 15 are connected by insertion or magnetic attraction. Specifically, when the first mating part 43 and the second mating part 15 are preferably connected by insertion, the first mating part 43 is preferably an insertion part, and the second mating part 15 is preferably an insertion groove. The insertion part is inserted into the insertion groove to realize the detachable connection between the fixing plate 4 and the main body 1. When the first mating part 43 and the second mating part 15 are preferably connected by magnetic attraction, the first mating part 43 is preferably a magnetic element, and the second mating part 15 is preferably a magnetic element. The magnetic element is used to generate magnetic attraction force. The magnetic element is made of ferromagnetic material, and the magnetic elements magnetically attract each other to realize the detachable connection between the fixing plate 4 and the main body 1. This detachable connection method of magnetic attraction or snap-fit ​​between the fixing plate 4 and the main body 1 improves the convenience for users when replacing the adhesive tape 3. Furthermore, this detachable connection method makes it easy to clean the insect killer 100 after mosquitoes accumulate in the first gap 121, thus improving the user experience.

[0035] In some embodiments, please refer to Figure 5The insect killer 100 includes an LED bead 5. The main body 1 has a light-transmitting hole 16, which communicates with a receiving cavity 11. The LED bead 5 is housed in the receiving cavity 11, and the light emitted by the LED bead 5 can be projected into the external environment through the light-transmitting hole 16. The LED bead 5 allows the insect killer 100 to attract mosquitoes by utilizing their phototaxis, thereby further enhancing the effectiveness of the insect killer 100 in using the adhesive tape 3 in conjunction with the air duct to kill mosquitoes.

[0036] Furthermore, taking advantage of the fact that mosquitoes have a higher phototaxis to ultraviolet light (315-400 nm) and blue light (wavelength 450 nm) than to ordinary white light, the aforementioned lamp beads 5 are preferably blue light lamp beads 51 and ultraviolet light lamp beads 52, with two corresponding light-transmitting holes 16. By utilizing the high sensitivity of mosquitoes to ultraviolet and blue light, the probability of mosquitoes approaching the insect killer 100 is increased, thereby improving the insect killer 100's mosquito-killing effect.

[0037] In some embodiments, please refer to Figure 5 The blue light bulb 51 and the violet light bulb 52 are arranged alternately, so that each bulb has its own independent illumination area (blue light area and violet light area) and a shared illumination area (indigo). This allows different areas to attract different types of mosquitoes. For example, mosquitoes highly sensitive to blue light are attracted to the blue light area corresponding to the blue light bulb 51, mosquitoes highly sensitive to violet light are attracted to the violet light area corresponding to the violet light bulb 52, and mosquitoes highly sensitive to indigo light are attracted to the shared area corresponding to both the violet light bulb 52 and the blue light bulb 51. This enhances the mosquito-killing effect of the insect killer 100.

[0038] In some embodiments, please refer to Figure 6 The insect killer 100 also includes a diffuser plate 6, which is located at the light-transmitting hole 16. The diffuser plate 6 is used to equalize the light and expand the visible range, attract mosquitoes from a distance, and also reduce the mosquitoes' avoidance behavior due to strong light, thereby improving the trapping effect of the insect killer 100.

[0039] It is understandable that the number of diffuser plates 6 corresponds to the number of light-transmitting holes 16, and will not be explained one by one here.

[0040] In some embodiments, please refer to Figure 5 and Figure 6 The insect killer 100 includes a circuit board 7 and a plug 8. The circuit board 7 is housed in the receiving cavity 11, and the plug 8 is disposed on the main body 1 and located on the side of the main body 1 away from the fixing plate 4 so that the insect killer 100 can be directly inserted into the socket. The circuit board 7 is electrically connected to the plug 8 and the fan 2 respectively. The LED bead 5 is electrically connected to the circuit board 7. The circuit board 7 is used to control the start and stop of the fan 2, the working time and power of the fan 2, etc., and to control the power supply current, brightness and working time of the LED bead 5, etc.

[0041] Furthermore, the circuit board 7 is equipped with three control modules to control the LED beads 5, the plug 8, and the fan 2. Specifically, these include a power supply module, an LED driver module, and a motor drive and control module. When the insect killer 100 is directly plugged into the socket, the power supply module on the circuit board 7 supplies power in two ways: one to the LED driver module and the other to the motor drive and control module. The LED driver module then rectifies and steps down the AC power through its step-down rectifier circuit to output DC power to drive the blue and ultraviolet LEDs. Finally, the motor drive and control module, after step-down rectification in its step-down rectifier circuit, supplies one power source directly to the motor's power drive integrated circuit and another to the microcontroller unit after step-down via a voltage regulator. The two power sources are then combined to control the fan 2 motor, allowing adjustment of the fan speed.

[0042] It should be noted that the type of plug 8 mentioned above includes, but is not limited to, any one of Type A to Type O. For example, in this embodiment, the type of plug 8 is preferably Type I. Using this type of plug 8 allows the insect killer 100 to be directly plugged into a power outlet in a location such as a wall, reducing the volume occupied by the insect killer 100 in actual use, and this installation method is more in line with actual household usage.

[0043] In some embodiments, please refer to Figure 5 and Figure 6 The main body 1 includes an upper cover 1a and a lower shell 1b. The air inlet 12 is located on the upper cover 1a, and the air outlet 13 is located on the lower shell 1b. The upper cover 1a and the lower shell 1b are closed to form the receiving cavity 11. The upper cover 1a is provided with a first half-hole 1a1, and the lower shell 1b is provided with a second half-hole 1b1. When the upper cover 1a and the lower shell 1b are closed, the first half-hole 1a1 and the second half-hole 1b1 form a plug through hole 17. The plug through hole 17 communicates with the receiving cavity 11 and is used for the electrical connection between the plug 8 and the circuit board 7.

[0044] Furthermore, the upper cover 1a includes a lampshade 1a2 and a middle frame 1a3. The middle frame 1a3 is provided with an extension hole 1a31 for the lamp bead 5 to extend out and be covered by the lampshade 1a2. The aforementioned light-transmitting hole 16 is located in the lampshade 1a2, and the aforementioned air inlet 12 is located in the middle frame 1a3. The extension hole 1a31 and the air inlet 12 are on the same surface of the middle frame 1a3 so that the light emitted by the lamp bead 5 through the lampshade 1a2 can cover the air inlet 12, ensuring that when mosquitoes are attracted to the insect killer 100 by the light, the air duct and sticker at the air inlet 12 can successfully kill the mosquitoes.

[0045] Understandably, the connection methods between the lampshade 1a2 and the middle frame 1a3 include, but are not limited to, screw connection, snap connection, magnetic connection, etc.

[0046] For example, in this embodiment, please refer to Figure 7 The lampshade 1a2 is connected to the middle frame 1a3 by a snap-fit. Specifically, the lampshade 1a2 is provided with multiple hooks 1a21, and the middle frame 1a3 is provided with multiple slots 1a32 on the side wall of the expansion hole 1a31. The hooks 1a21 engage with the slots 1a32, thereby realizing the detachable connection between the middle frame 1a3 and the lampshade 1a2.

[0047] Furthermore, the middle frame 1a3 extends a reinforcing arm 1a33 from the side wall of the extension hole 1a31. The reinforcing arm 1a33 is used to guide the lampshade 1a2 to be inserted into the middle frame 1a3 to improve the connection strength between the lampshade 1a2 and the middle frame 1a3. The end of the reinforcing arm 1a33 away from the middle frame 1a3 is provided with an abutment platform 1a331, which is used to place the aforementioned diffuser.

[0048] It should be noted that the number of reinforcing arms 1a33 is consistent with the number of light-transmitting holes 16, and the length of the reinforcing arms 1a33 is consistent with the distance between the light-transmitting holes 16 and the middle frame 1a3 when the lampshade 1a2 is installed on the middle frame 1a3, so as to ensure that the diffuser placed on the abutment platform 1a331 can correspond to the light-transmitting holes 16.

[0049] In this application, the insect killer 100 includes a main body 1, a fan 2, and adhesive tape 3. The main body 1 is provided with a receiving cavity 11, an air inlet 12, and an air outlet 13. The air inlet 12 and the air outlet 13 are both connected to the receiving cavity 11. The fan 2 is placed in the receiving cavity 11 and can form an air duct with the air outlet 13 and the air inlet 12. The fan 2 is used to accelerate the airflow in the receiving cavity 11. The adhesive tape 3 is placed outside the main body 1 and can kill mosquitoes in a natural state. The adhesive tape 3 is adjacent to the air inlet. The adhesive tape 3 positioned adjacent to the air inlet 12 allows it to be located within the aforementioned air duct. This enables mosquitoes to be carried to the adhesive tape 3 by the airflow within the air duct after entering it, thereby increasing the probability of killing mosquitoes near the adhesive tape 3. Furthermore, this method of increasing the killing probability of the adhesive tape 3 by relying on the air duct is not affected by airflow compared to the insect killer 100 that relies solely on the ultraviolet lamp in conjunction with the adhesive tape 3. Compared to the electric shock insect killer 100, it is also quieter and avoids disturbing the user.

[0050] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this utility model; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
