DETAILED DESCRIPTION

[0044] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, Figures 1 to 19The structure of an intelligent mosquito killer lamp according to an embodiment of the present invention is schematically shown. The present invention will be further described below in conjunction with specific embodiments.

[0045] Example 1

[0046] like Figure 1-Figure 7 As shown, the present invention provides an intelligent mosquito-killing lamp, which includes a lamp body 1 and an air inlet cover 3 arranged inside the lamp body 1, a wind cover opening and closing system 2 is installed inside the air inlet cover 3, a No. 2 wind cover 4 and a mosquito collecting device 5 are also provided inside the lamp body 1, the No. 2 wind cover 4 is located between the air inlet cover 3 and the mosquito collecting device 5, a main fan 41 is provided inside the No. 2 wind cover 4, and a bottom cover 6 is also installed at the bottom of the lamp body 1.

[0047] In this embodiment, the air hood opening and closing system 2 is composed of an upper cover 201, an upper blade 202, a rotating block 203, and a stepper motor 204. The rotating block 203 is installed on the output shaft of the stepper motor 204. The four positions of the rotating block 203 are all matched with the upper blade 202. The upper blade 202 is movably connected to the upper cover 201. The upper blade 202 is driven to rotate by the rotation of the rotating block 203 to realize the opening and closing of the air outlet. The stepper motor 204 is fixed at the center position of the inner top surface of the air inlet hood 3, and the upper cover 201 is built into the air inlet hood 3. A purple-blue light circuit board 200 is provided at the center position of the top surface of the upper cover 201.

[0048] The range of A, the radius of which is centered around the microwave sensor and microphone, is used as the range for identifying mosquito activities. For the control logic, please refer to the attached Figure 19 .

[0049] Condition one:

[0050] ①When a mosquito enters this range and no signal is detected by the microwave sensor, the fan turns off.

[0051] ② If the microwave sensor detects a signal, the processor calculates the real-time distance change of the mosquito:

[0052] As the distance increases, it means that the target may be moving away, and the program returns to continue detecting whether there is a target within the range; as the distance decreases, the data provided by the microphone is judged at the same time. If the conditions are met, the fan is started. After the fan is started, the program returns to the microwave sensing stage and repeatedly detects whether there is still a target.

[0053] Condition two:

[0054] ①The microphone detects the degree of match between the target sound and the set value in the system.

[0055] ② If the detection does not match, the next step is for the microwave sensor to detect whether there is a signal. If not, the fan is turned off. If so, continue to step one of condition one.

[0056] ③ If they match, the Doppler effect is used to determine the changes in the sound wave frequency and amplitude: if both increase, and the distance detected by condition 1 decreases, the fan is started; if both decrease, the distance increases as condition 1 is met, and no signal is detected afterwards, the fan is turned off.

[0057] After the main fan 41 is started, two conditions are determined.

[0058] After the main fan 41 is started, the system sends a signal to the stepper motor 204, the rotating block 203 rotates to open the upper blade 202 of the air inlet cover 3, and when the main fan 41 is turned off, the rotating block 203 rotates in the opposite direction and the upper blade 202 is closed.

[0059] Specifically, four equidistantly arranged fan-shaped holes 011 are provided on the upper cover 201. The fan-shaped holes 011 are arranged opposite to the upper blade 202. A shaft sleeve 012 is provided between two adjacent fan-shaped holes 011. A rotating shaft 021 is provided on one side of the upper blade 202. A movable block 022 is fixed to one end of the upper blade 202 facing the rotating block 203. The rotating shaft 021 is movably connected to the shaft sleeve 012. Four inclined grooves 031 are provided on the outer wall of the rotating block 203. The movable block 022 passes through the inclined groove 031 and the two are movably matched.

[0060] Since the rotating shaft 021 of the upper blade 202 is movably connected to the shaft sleeve 012 of the upper cover 201, and the movable block 022 cooperates with the inclined groove 031, the rotating block 203 will rotate under the drive of the stepping motor 204. Since the inclined groove 031 has an inclination, the inclined groove 031 will generate a force on the movable block 022, thereby driving the upper blade 202 to deflect, thereby blocking or opening the fan-shaped hole 011.

[0061] The problem solved by this embodiment is that the existing mosquito killer lamp has a simple control logic. As long as the function is turned on, the fan is always on. The present invention forms an efficient fan start / shutdown control system through the cooperation of two components, a microwave sensing sensor and a microphone. The opening and closing of the air inlet cover of the air intake system can be controlled through the judgment of the microwave sensing sensor and the microphone. Compared with the existing technology, this technology can operate efficiently while saving energy, and minimize unnecessary fan noise. It is particularly beneficial for use in sleeping at night. The addition of the wind cover opening and closing system cooperates with the mosquito catching logic to better protect the internal structure and prevent mosquitoes from being sucked into the interior and still escaping.

[0062] Example 2

[0063] like Figures 1-16As shown, based on the first embodiment, the mosquito collecting device 5 described in the first embodiment includes an inner lower cover 500, a drawer 501 is built into the inner lower cover, an inner upper cover 502 is provided above the drawer 501, and a four-bar linkage 1 503 and a four-bar linkage 2 504 are provided between the inner upper cover 502 and the drawer 501. The four-bar linkage 1 503 and the four-bar linkage 2 504 cooperate to fix a filter bag 505, and the filter bag 505 is recessed inwardly into the drawer 501.

[0064] In this embodiment, an air inlet is provided at the center of the inner upper cover 502 , and a stop block 521 is fixed to a side of the inner upper cover 502 facing the drawer 501 .

[0065] In this embodiment, a positioning column 511 is vertically fixed to the top surface of the drawer 501 , and the positioning column 511 is configured to be positioned with the four-bar linkage mechanism 1 503 and the four-bar linkage mechanism 2 504 .

[0066] In this embodiment, the four-bar linkage mechanism 503 is composed of two No. 1 connecting rods 531 and two No. 4 connecting rods 530 arranged alternately. The top surfaces of the No. 1 connecting rod 531 and the No. 4 connecting rod 530 are each provided with a No. 1 magnet 532, and both ends of the bottom surface are fixed with alignment columns 533. One end of one of the No. 1 connecting rods 531 is fixed with a limiting axis 534.

[0067] In this embodiment, the four-bar linkage mechanism 2 504 is composed of two No. 2 connecting rods 541 and two No. 3 connecting rods 542 arranged alternately. The No. 2 connecting rod 541 and the No. 3 connecting rod 542 are both provided with an alignment slot 543 that engages with the alignment column 533. A torsion spring 545 is provided between one of the No. 2 connecting rods 541 and the No. 3 connecting rod 542.

[0068] The combination of the alignment slot 543 and the alignment post 533 is used for positioning and assembling the four-bar linkage 1 503 and the four-bar linkage 2 504 .

[0069] When in use, first separate the four-bar linkage 1 503 and the four-bar linkage 2 504, place the filter bag on the four-bar linkage 2 504, and position it through the alignment column 533 and the alignment slot 543. Since the No. 2 and No. 3 links are also equipped with No. 1 magnets, the positive and negative poles of the No. 1 magnet in the four-bar linkage 2 are opposite to those of the No. 1 magnet in the four-bar linkage 1. Based on the attraction between opposite poles of magnets, the filter bag can be magnetically fixed.

[0070] After assembling the four-link mechanism 1 503 and the four-link mechanism 2 504 and assembling them with the positioning column 511 of the drawer 501, it can be used;

[0071] When the entire drawer assembly is placed in the mosquito repellent lamp, the limit shaft 534 of the four-bar linkage 1 503 hits the stop block 521 of the inner upper cover 502, and the two four-bar linkages are pulled to expand. Similarly, when the drawer 501 is pulled out, the torsion spring 545 installed in the four-bar linkage 2 504 will automatically return to the principle closed state (such as Figure 12 shown).

[0072] The problem solved by this embodiment is that the existing mosquito killer lamp is relatively simple, with only a simple mosquito storage drawer. The present invention uses a four-link mechanism as a retractable bracket to achieve free opening and closing of the filter bag. Through this technology, the drawer box can be pulled out when the mosquito bag is full to prevent mosquitoes from escaping or falling out easily, thereby increasing hygiene and safety and making cleaning more convenient and simple.

[0073] Example 3

[0074] like Figures 1-18 As shown, the difference from embodiment 1-2 is that an air flow meter fan a and an air flow meter circuit board b are installed on the inner bottom of the drawer 501.

[0075] ① When the main fan 41 is turned on, the air intake volume is a fixed value A.

[0076] ② When the number of mosquitoes in the filter bag 505 reaches a certain level, the air volume value sensed by the rotation of the air volume meter blades is calculated as B.

[0077] ③B<A, when B is at the set value, it means the storage capacity has reached full filling, reminding the user to replace and clean.

[0078] The problem solved by this embodiment is that the existing mosquito killer lamps have no storage capacity prompt function. The present invention uses the air volume difference principle. When the incoming air volume passes through the filter bag, if there are many mosquitoes, the air volume will decrease, the air volume meter fan blades will rotate, and the difference between the current air volume and the incoming air volume will be calculated. When it reaches a certain value, it can be determined that the storage capacity is full. The current status can be discovered in time, which is conducive to timely cleaning of the filter bag and keeping the mosquito killer lamp in an effective working state.

[0079] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
