Description

Technical Field

[0001] The utility model relates to an insecticidal lamp, in particular to an air suction type insecticidal lamp. Background Art

[0002] The working principle of a wind-suction insecticidal lamp is to attract mosquitoes and other pests by emitting a special spectrum of wavelengths in the 365-420 wavelength range. The negative pressure generated by the fan draws the pests into a collection chamber. Traditional wind-suction insecticidal lamps are ineffective in killing insects. This is mainly because when the fan rotates at a high speed, the loud noise it produces scares the pests, causing them to avoid approaching the insecticidal lamp and never enter the fan's range of influence, resulting in poor attracting and, consequently, poor insecticide results. Slowing the fan speed also fails to generate negative pressure, preventing the pests from being drawn into the collection chamber. Therefore, this application proposes a wind-suction insecticidal lamp to address this problem. Utility Model Content

[0003] The purpose of the present invention is to provide a wind-suction insecticidal lamp to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a wind-suction insecticidal lamp, comprising a bracket, a top cover box, an insect-attracting lamp, a fan rack, a fan and a collection bag, the top cover box being installed on the top of the bracket, the insect-attracting lamp being installed at the bottom of the top cover box, and the fan rack being installed below the top cover box, the fan being installed in the air duct of the fan rack, and a guide tube being provided at the outlet end of the air duct, and the collection bag being installed at the guide outlet of the guide tube.

[0005] The connecting plate at the side end of the fan is installed in the air duct of the fan frame through an elastic fastening mechanism. The elastic fastening mechanism includes a latch post, a spring and a knob. The spring is sleeved on the latch post. The spring is located below the limit ring fixed on the latch post. The latch post is inserted into the through groove of the connecting plate at the side end of the fan and the inner ring fixing plate at the outlet end of the air duct of the fan frame, and a threaded groove is provided at the bottom of the latch post. The knob is screwed into the threaded groove of the latch post.

[0006] The guide tube is an inverted cone structure with a large diameter at the upper end and a small diameter at the lower end.

[0007] A check ring is provided at the bag opening of the collection bag.

[0008] A hand-blocking grille plate is provided at the air duct inlet of the fan frame.

[0009] A controller is arranged in the top cover box, and the controller is electrically connected to the insect attractant lamp and the fan.

[0010] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0011] 1. The present invention makes improvements based on the problems in the background technology. The applicant sets the speed of the fan by timing the controller. When the fan is at a low speed, the noise is low, and mosquitoes and insect pests are not frightened and easily enter the fan's range. After a period of low speed, the fan automatically runs at a high speed. The high-speed rotation of the fan forms a wind vortex, which in turn forms a negative pressure, and the pests are quickly sucked into the collection bag. The present invention cleverly solves the problem that the fan is constantly rotating at a high speed and makes a lot of noise, which makes it difficult for mosquitoes and insects to enter the fan range by timing the high and low speed rotation of the fan.

[0012] 2. A check ring is provided at the opening of the collection bag of the present invention. The check ring can further prevent the mosquitoes and insects sucked into the collection bag from flying out of the collection bag and into the guide tube, thereby preventing the airflow from forming turbulent flow due to the mosquitoes and insects entering the guide tube, thereby ensuring smooth airflow;

[0013] 3. The connecting plate at the side end of the fan of the utility model is installed in the air duct of the fan frame through an elastic fastening mechanism. The elastic fastening mechanism includes a latch column, a spring and a knob. The present application ensures the stable rotation of the fan while facilitating the disassembly and installation of the fan, thereby making the entire air suction insecticidal lamp more applicable.

[0014] 4. The guide tube of the utility model has an inverted cone structure with a large diameter at the upper end and a small diameter at the lower end. This structural design makes the air flow velocity faster and can form a stronger negative pressure, thereby having a stronger inhalation and insecticidal effect on mosquito pests;

[0015] 5. The utility model has a simple structure, high efficiency, low noise, no pollution and no odor, and is more suitable for home use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1 、 2 , 3, 4 and 7, a wind-suction insecticidal lamp, comprising a bracket 1, a top cover box 2, an insect-attracting lamp 3, a fan rack 4, a fan 5 and a collecting bag 6. The top cover box 2 is mounted on the top of the bracket 1, the insect-attracting lamp 3 is mounted on the bottom of the top cover box 2, and the fan rack 4 is mounted below the top cover box 2. The fan 5 is mounted in the air duct of the fan rack 4, and a guide tube 7 is provided at the outlet end of the air duct. A collecting bag 6 is installed at the guide outlet of the guide tube 7. A controller is provided in the top cover box 2, and the controller is electrically connected to the insect-attracting lamp 3 and the fan 5. The controller in this application is a timing controller (the controller is a common device on the market. The controller is often used as a control component of products in this field. Its structure and principle are common knowledge in this field. Those skilled in the art can Make a selection as needed, no need to elaborate here), the controller can adjust the time interval between high-speed and low-speed rotation of the fan 5 as needed. This application sets the fan 5 to rotate at low speed for four minutes and then at high speed for one minute through the controller. After the insecticidal lamp is started, during the low-speed rotation time, the fan 5 makes little noise, and mosquitoes and other pests enter the area affected by the fan 5 under the action of the insect-attracting lamp 3. After the low-speed rotation time, the fan 5 instantly enters high-speed rotation to form a wind vortex, thereby forming negative pressure, and the pests are quickly sucked into the collection bag 6. This application can be provided with a solar panel, and the solar panel is electrically connected to the controller. The solar panel realizes photoelectric conversion to provide power, and can also be directly connected to municipal electricity.

[0027] The guide tube 7 is an inverted cone structure with a large diameter at the upper end and a small diameter at the lower end. This structural design allows the air flow rate to change from small to large (the smaller the diameter, the greater the air flow rate, and the lower the air pressure), which can form a stronger negative pressure, thereby having a stronger inhalation insecticidal effect on mosquito pests.

[0028] A check ring 10 is provided at the bag opening of the collection bag 6. The check ring 10 can further prevent the pests that are sucked into the collection bag 6 and not killed from flying out of the collection bag 6 and entering the guide tube 7. If there is no check ring 10 in the collection bag 6, the pests will be more likely to fly out of the collection bag 6. The check ring 10 has an arc-shaped structure, which allows the killed pests to roll to the bottom of the collection bag 6, thereby preventing the airflow from forming a turbulent state due to mosquito pests entering the guide tube 7, thereby ensuring smooth airflow.

[0029] A hand-blocking grille plate 11 is provided at the air duct inlet of the fan frame 4 to prevent children from putting their hands into the air duct of the fan frame 4 and to prevent the fan 5 from injuring children's fingers.

[0030] Example 2: Please refer to Figure 5 and 6 On the basis of implementing the technical solution 1, the connecting plate at the side end of the fan 5 is installed in the air duct of the fan frame 4 through an elastic fastening mechanism 8. The elastic fastening mechanism 8 includes a latch column 81, a spring 82 and a knob member 83. The latch column 81 is sleeved with a spring 82. The spring 82 is located below the limit ring 9 fixed on the latch column 81. When the fan 5 needs to be installed, the latch column 81 is inserted into the through groove of the connecting plate at the side end of the fan 5 and the inner ring fixing plate at the air duct outlet end of the fan frame 4. A threaded groove is provided at the bottom of the latch column 81. The knob member 83 is screwed into the threaded groove of the latch column 81, and the rotation The screwing end of the button 83 is provided with a limit part 12, which is similar to a U-shaped structure. On the one hand, it is convenient to screw the knob 83, and at the same time, it can limit the pin column 81 so that the fan 5 is installed in the air duct of the fan frame 4. The elastic force of the spring 82 can strengthen the cooperation between the pin column 81 and the knob 83, thereby enhancing the firmness of the installation of the fan 5. When the fan 5 needs to be disassembled, press the pin column 81 down hard to move it downward, and then screw the knob 83 out of the threaded groove at the bottom of the pin column 81, and finally pull out the pin column 81. At this time, the fan 5 can be taken out.
