Description

Mosquito killer

Technical Field

The present application relates to an improved carrier trap.

Background

Mosquitoes are one form of vector. The vector refers to an insect or animal that transmits a disease from one person to another. Female mosquito bites transmit dangerous diseases such as malaria, dengue fever, and West Nile virus (West Nile virus). The female mosquito bites the animal or human and draws a small amount of blood for reproduction. The blood contains proteins that allow the female mosquito to lay eggs. After this time, the female mosquitoes lay their eggs in water. The larvae then hatch from the eggs. The larvae live in water and the organic matter is filtered out (obtained) from the water to sustain life. The larvae then turn into pupae, which turn into adult mosquitoes (adult mosquitoes) and fly away. The period of the egg growth into adult mosquitoes is about one week.

US6298011Bl discloses a method of killing mosquito larvae. The method includes immersing an acoustic transducer (acoustic transducer) in a body of water containing mosquito larvae and energizing the acoustic transducer to induce a resonant frequency in the body of water. The resonance frequency resonates with the air sacs of mosquito larvae, which then injure the surrounding tissues, resulting in death of mosquito larvae.

US20140202961Al discloses a system for depleting (reducing) target organisms in water. The system includes a waterproof transducer configured to penetrate a water-containing vessel or a water-filled vessel with low intensity sound at one or more ultrasonic frequencies for a time sufficient to prevent at least 90% of a target organism from maturing. The target organism may be referred to as mosquito larvae. In one implementation, a portable system for consuming a target organism in water includes a control system and a plurality of waterproof transducers. The system is configured to cause sound to penetrate a surface layer of water, the sound having a sound frequency range from about 40 kilohertz to about 100 kilohertz and having a power concentration range of about 35 milliwatts per milliliter to about 100 milliwatts per milliliter for a duration of about 1 second to about 100 seconds.

Disclosure of Invention

It is an object of the present application to provide an improved mosquito eradication device.

The present application provides an improved mosquito eradication device for providing a suitable breeding ground for mosquito larvae and for destroying or killing the larvae.

The mosquito eradication device includes a container for collecting and storing rainwater. The stored rain (usually stationary) provides a suitable breeding ground for mosquito larvae.

The mosquito eradication apparatus further includes an Ultraviolet (UV) light generation unit to generate UV light, and to emit or transmit the generated UV light toward the container. UV light refers to light having a wavelength near or in the ultraviolet range of 10 nanometers (nm) to 400 nm. The transmitted UV light will attract the female mosquitoes to lay eggs in the water in the container. The eggs later grow into mosquito larvae. Since mosquitoes are more active at night, the UV light generating device is often powered on at night.

The mosquito eradication device also includes a water level sensor for measuring a water level in the container. The water level sensor may measure the depth of the water level or may determine a range of depths of the water level.

The mosquito eradication apparatus further includes an ultrasonic wave generation unit for generating an ultrasonic wave having a predetermined frequency or wavelength. The operating frequency of the ultrasonic waves may exceed 20 khz. The generated ultrasonic waves are directed to the water in the container where mosquito larvae multiply. The transmitted ultrasonic waves resonate with air bags of the mosquito larvae, so that tissues around the air bags are damaged, and the mosquito larvae are killed.

The mosquito eradication device also includes a control unit adapted to receive a measurement of the water level in the container from the water level sensor.

After the control unit receives the water level measurement value, it determines the duration of the ultrasonic wave transmission based on the received water level measurement value.

The duration is determined such that the sound energy of the ultrasonic waves is sufficient to kill mosquito larvae located at different locations or positions in the water in the container, even when the larvae are located at the farthest positions from the ultrasonic wave generating unit. When ultrasonic waves propagate in water, their amplitudes are attenuated due to absorption and scattering of the sound waves by particles or impurities in the water, resulting in a loss of acoustic energy. This attenuation or energy loss also increases with the distance the ultrasound wave travels. This means that the sound energy received at the position farthest from the ultrasonic wave generating unit is the smallest. To kill the furthest located mosquito larvae, the duration of the ultrasonic wave is typically determined by the furthest distance the ultrasonic wave propagates.

This maximum distance also corresponds to a measure of the water level in the container. The higher the water level measurement, the longer the furthest distance and vice versa. In other words, the control unit uses the measured value of the water level to determine the duration of the ultrasonic emission.

The control unit then activates or excites the ultrasound generating unit to transmit ultrasound at a predetermined frequency for said determined duration. The mosquito larvae in the water are then subjected to ultrasonic waves, wherein the ultrasonic waves injure the larvae sufficiently to prevent the mosquito larvae from maturing.

In short, the improved mosquito eradication apparatus effectively attracts female mosquitoes to lay eggs in water to grow into larvae, and then effectively kills the larvae by sending ultrasonic waves for a sufficient time determined according to the water level of the water in the container, which may vary with time. The duration can be shortened when the water level in the container is low. This saves energy compared to other devices that transmit ultrasound for a fixed duration.

The ultrasonic wave generating unit may be disposed near the bottom of the container. In other words, the ultrasonic-wave generating unit may be disposed at an outer surface of the bottom of the container, below the bottom of the container, or at a position inside the container and near the bottom of the container. This makes the implementation easy.

In one implementation, the ultrasonic wave generating unit provides ultrasonic waves at a predetermined frequency of about 42 kilohertz and transmits the ultrasonic waves at a power of about 50 watts. The duration of the ultrasonic wave transmission ranges from 5 minutes to 20 minutes.

The ultrasonic wave generating unit may be deactivated when the measured or sensed water level is substantially zero. In other words, the ultrasonic wave generating unit is not excited when mosquito larvae are substantially absent. This will then save energy and operating costs.

The UV generating unit may be disposed adjacent to or within the container. This allows the female mosquitoes to fly towards the UV generating device and easily reach the container for spawning in the water in the container.

The UV generating unit may comprise a plurality of low cost and readily available UV light emitting diodes.

In one embodiment, the mosquito eradication apparatus further includes a light sensor for detecting the absence of light and sending a corresponding detection signal to the control unit based on the detection. The control unit then activates the UV generating unit according to the detection signal. This allows the UV generating unit to send UV light at night to effectively attract mosquitoes (most active at night). In order to save energy, the UV generating unit is not activated during the day to save energy.

The mosquito eradication device also includes a battery module for supplying power to the mosquito eradication device.

The mosquito eradication device may also include a solar module for selectively charging the battery module. The solar module may refer to a solar panel or a solar cell assembly, which includes a plurality of solar cells. The solar cell plays a role of converting solar radiation into electric energy to charge the battery module. This enables the mosquito eradication device to self-maintain power so that it can be deployed in remote areas where power generation is inconvenient.

The mosquito eradication device also includes an alternating current-to-direct current (AC/DC) adapter module for receiving energy from an external power source and for selectively charging the battery module. The AC/DC adapter module may be electrically connected to an AC power grid for receiving an AC voltage. The AC/DC adapter module then converts the received AC voltage to a DC voltage for charging the battery module. This enables the mosquito eradication device to be powered even when sunlight is sufficient.

The application also provides a method for operating the mosquito killing device. The method includes the steps of collecting and storing rain water in a container, and transmitting UV light to the container to attract female mosquitoes to lay eggs and breed mosquito larvae. The method further includes the steps of measuring the water level of the water in the container and determining the duration of the transmission of the ultrasonic waves based on the measured value of the water level. The method further comprises the steps of generating ultrasonic waves at a predetermined frequency and transmitting the generated ultrasonic waves for a determined duration of time to prevent mosquito larvae from maturing.

The method may further comprise the step of measuring the absence of light for activating the transmission of UV light.

The method may further include the step of selectively charging a battery module of the mosquito eradication device with the solar module.

In the following description, details are provided to describe embodiments of the present application. It will be apparent, however, to one skilled in the art that the embodiments may be practiced without these specific details.

Certain portions of the embodiments have similar components. The similar components may have the same name or similar component numbers. The description of one component applies to another similar component as appropriate to reduce repetition of text without limiting the disclosure.

Fig. 1 shows a modified mosquito eradication device (mosquito operation device) 1. The mosquito eradication device 1 includes a mosquito killer 10 and a power assembly 5. The mosquito killer 10 includes a housing 13, a mosquito capture module 16, and a mosquito eradication module 19. The mosquito capture module 16 is attached to the outer surface of the mosquito eradication module 19. The mosquito capture module 16 is surrounded by the housing 13 such that the housing 13 is in contact and touching contact with the outer surface of the mosquito eradication module 19. The power assembly (power assembly)5 is electrically connected to the mosquito extermination module 19 electrically connected to the mosquito capture module 16.

The power assembly 5 includes a solar panel 53 and an alternating current-direct current (AC/DC) adapter module 60.

The solar panel 53 has an output electrically connected to the mosquito eradication module 19. In one implementation, the solar panel has a Direct Current (DC) voltage output of 18 volts.

The AC/DC adapter module 60 has an input adapted to be electrically connected to an AC power grid 61 and an output electrically connected to the mosquito eradication module 19.

The housing 13 has a hollow body of a substantially rectangular parallelepiped. The hollow body includes a top surface, four side surfaces, and a cavity (which is surrounded by the top surface and the four side surfaces). The top surface is provided with openings and the side surfaces are provided with a plurality of openings or slits.

Referring to fig. 2, the mosquito trap module 16 includes a mosquito propagation container 22 and an Ultraviolet (UV) light generating unit 25 placed inside the mosquito propagation container 22.

The container 22 is substantially cylindrical and it is made of metal. In a general sense, the container 22 may also be made of other materials. The container 22 includes a plurality of slits 28 disposed near the edges of the container 22. Each slit 28 is covered by a water filter.

As shown in fig. 3, the ultraviolet light generating unit 25 includes a plastic housing 32, a control Printed Circuit Board (PCB)37, a plurality of ultraviolet light emitting diodes (UV LEDs) 42, a light sensor 38, a water level sensor 40, and a microcontroller 48. The UV LED 42, water level sensor 40 and microcontroller 48 are mounted to the control PCB 37, while the light sensor 38 is mounted on the outer surface of the plastic housing 32. The control PCB 37 is located within the housing 32 near a central location within the container 22. The microcontroller 48 is electrically connected to the UV LED 42, the light sensor 38 and the water level sensor 40.

In one implementation, the microcontroller 48 is adapted to process 8-bit, 16-bit, or 32-bit data, and it has an embedded memory module. The plurality of UV LEDs 42 includes 8 UV LEDs. The light sensor 38 includes an ambient light sensing device (ambient light sensing device), while the water level sensor 40 includes a capacitive sensing device (capacitive sensing device).

As for the mosquito eradication module 19, it includes a substantially rectangular parallelepiped case 41, a main Printed Circuit Board (PCB)55, an ultrasonic wave generation device 43, and a battery module 56. A part of the ultrasonic wave generating device 43 and the battery module 56 are disposed on the main PCB 55 within the case 41. As best seen in fig. 4, the battery module 56 is electrically connected to the solar cell panel 53, the AC/DC adapter module 60, and the ultrasonic wave generating device 43.

Battery module 56 includes a solar charger 59 having a Maximum Power Point Tracking (MPPT) device, a rechargeable battery 62 and a voltage regulator 65. The solar charger 59 is electrically connected to the battery 62. The battery 62 is electrically connected to a voltage regulator 65, which is electrically connected to the ultrasonic wave generating device 43. The voltage regulator 65 is also electrically connected to the microcontroller 48, the UV LED 42, the light sensor 38 and the water level sensor 40 of the mosquito capture module 16.

In one implementation, the battery module 56 includes a solar charger with a current limiting circuit, a lithium ion battery with an operating voltage of 11.1 volts, and a 5 volt voltage regulator.

The battery module 56 also includes a single-pole-double-throw (SPDT) switch, which is not shown in the drawings for simplicity. The SPDT switch includes a first input terminal, a second input terminal, and an output terminal. The first input terminal is electrically connected to the AC/DC adapter module 60, while the second input terminal is electrically connected to the solar cell panel 53. The output terminal is electrically connected to a solar charger 59.

The ultrasonic wave generating device 43 includes a driving unit 46, a transformer 45, and an ultrasonic transducer 47. The driving unit 46 is electrically connected to the voltage regulator 65 and the transformer 45. The transformer 45 is electrically connected to the ultrasonic transducer 47. As shown in fig. 3, the driving unit 46 and the transformer 45 are mounted on the main PCB 55 while the ultrasonic transducer 47 is connected to the outer surface of the bottom of the container 22.

In use, the mosquito eradication device 1 is typically placed in an area, such as a wet area, that provides suitable habitat for mosquitoes to breed.

The openings and slits in the sides of the housing 13 serve to block and prevent foreign objects (e.g., leaves) from falling or entering the mosquito propagation container 22 while allowing mosquitoes to fly through them. The opening of the top surface of the housing 13 also allows rainwater to flow through.

The mosquito propagation container 22 serves to receive rainwater and store the received rainwater. The stored rainwater provides a breeding place for female mosquitoes to lay eggs and the mosquitoes to grow into larvae and then become pupae.

The slit 28 and the filter near the edge of the container 22 serve to allow water to exit the container 22 when the container 22 overflows, while the filter serves to prevent mosquito eggs, larvae and pupae in the water from leaving the container 22.

The ultrasonic wave generating device 43 provides a standby mode and an operation mode.

In the standby mode, the ultrasonic wave generating device 43 is not activated and not excited.

In the operating mode, the ultrasonic wave generating means 43 is activated or energized. The excited ultrasonic wave generating means 43 then generates ultrasonic waves having a predetermined frequency or wavelength for a specified duration, wherein the generated ultrasonic waves are directed to the water in the container 22.

Specifically, the driving unit 46 of the ultrasonic wave generating device 43 is excited to generate an alternating current signal having a predetermined frequency or wavelength for a certain duration, and transmits the generated electric signal to the transformer 45. The transformer 45 then receives the transmitted electrical signal and subsequently sends a corresponding amplified electrical signal (having an amplified amplitude) to the ultrasonic transducer 47. The ultrasonic transducer 47 then receives the corresponding amplified electrical signal and then converts the corresponding amplified electrical signal into an ultrasonic signal or wave for transmission toward the water within the tank 22.

In one implementation, the driving unit 46 is adapted to generate an electrical signal having a predetermined frequency of 42 Kilohertz (KHZ) for driving the transformer 45. Subsequently, transformer 45 sends a corresponding amplified electrical signal of 300 volts or 300VAC to ultrasonic transducer 47. Then, the ultrasonic transducer 47 generates 42KHZ ultrasonic waves having a power of about 50 watts (W) for transmission.

In another implementation, the drive unit 46 is adapted to generate an electrical signal having a predetermined frequency (in the range of 41KHZ to 43 KHz).

The memory module of microcontroller 48 is used to store instructions of one or more software programs. Microcontroller 48 is used to execute instructions that control or direct the operation of the electrical components of mosquito killer 10.

The light sensor 38 is adapted to detect the presence or absence of light and to send a corresponding detection signal to the microcontroller 48 based on the detection of light. The light sensor 38 sends a daytime detection signal when the light sensor 38 detects the presence of light that normally occurs during the daytime, and sends a nighttime detection signal when the light sensor 38 detects the absence of light (particularly at night).

The microcontroller 48 then receives the transmitted detection signal and then activates or deactivates the UV LED 42 in accordance with the received detection signal. If the microcontroller 48 receives the nighttime detection signal, the microcontroller 48 then energizes the UV LED 42. If the microcontroller 48 receives the daytime detection signal, the microcontroller 48 does not energize the UV LED 42.

When the UV LED 42 is energized, the UV LED 42 emits UV light to attract mosquitoes to fly toward the container 22. The female mosquitoes then lay eggs in the water in the container 22.

When the UV LED 42 is not energized, the UV LED 42 does not emit any UV light.

The water level sensor 40 is used to measure the water level within the container 22 and to send the measured value of the water level to the microcontroller 48.

The microcontroller 48 then receives the measured value of the water level and then determines the duration for energizing the ultrasonic-wave generating means 43 on the basis of the received measured value of the water level.

The duration is determined such that the sound energy of the ultrasonic waves is sufficient to kill mosquito larvae located at different locations or positions in the water of the container 22, even when the larvae are located furthest from the ultrasonic transducer 47 of the ultrasonic wave generating device 43. When ultrasonic waves propagate in water, their amplitudes are attenuated due to absorption and scattering of the sound waves by particles or impurities in the water, resulting in a loss of acoustic energy. Attenuation or energy loss also increases with the distance that the ultrasound wave travels. This means that the sound energy received at the furthest position from the ultrasonic transducer 47 is the smallest. To kill the furthest located mosquito larvae, the duration of the ultrasonic wave is typically determined by the furthest distance the ultrasonic wave propagates.

The maximum distance also corresponds to a measure of the water level in the reservoir 22. The higher the water level measurement, the longer the furthest distance and vice versa. In other words, the microcontroller 48 uses the water level measurement to determine the duration of time for which the ultrasonic waves are transmitted.

In one implementation, the determined duration is zero if the water level measurement is substantially zero or below the first measurement range. If the water level measurement is within the first measurement range, the duration of the determination is 5 minutes. If the water level measurement is within a second measurement range that is higher than the first measurement range, the determined duration is 10 minutes. If the water level measurement is within a third measurement range that is higher than the second measurement range, the determined duration is 15 minutes. If the water level measurement is within a fourth measurement range that is higher than the third measurement range, the determined duration is 20 minutes.

After this, the microcontroller 48 activates and excites the ultrasound generating device 43 for a certain time duration.

Then, the excited ultrasonic wave generating means 43 generates ultrasonic waves at a predetermined frequency or wavelength for a certain duration, and then emits the generated ultrasonic waves toward the water of the container 22.

The emitted ultrasonic waves then propagate through the water in the container 22. The ultrasonic waves then resonate with the air sacs of the mosquito larvae and damage the tissue surrounding the air sacs for a determined duration of time to prevent the mosquito larvae from maturing or kill the mosquito larvae.

With respect to the solar panel 53 and the AC/DC adapter module 60, they are used to provide power to the mosquito killer 10. The mosquito repellent 10 can be placed in two different power modes, an AC/DC adapter mode and a solar cell mode.

In the AC/DC adapter mode, the AC/DC adapter module 60, which is electrically connected to the AC grid 61, is electrically connected to the solar charger 59 through the SPDT switch.

Specifically, the user places the SPDT switch in a first position with its first input terminal connected to its output terminal and its second input terminal not connected to its output terminal. The AC/DC adapter module 60 is then electrically connected to the first input terminal of the SPDT switch, to the output terminal of the SPDT switch, and to the solar charger 59. The AC/DC adapter module 60 then receives an Alternating Current (AC) voltage from an AC power grid 61 and then converts the AC voltage to a DC voltage for transmission to the first input terminal, the output terminal, and the solar charger 59.

The solar charger 59 then receives the DC voltage from the AC/DC adapter module 60 and then sends the DC voltage to charge the rechargeable battery 62. The battery 62 then supplies a predetermined voltage to the voltage regulator 65. The voltage regulator 65 then receives a predetermined voltage and then provides a voltage having a predetermined constant level, for example 5 volts, for powering the microcontroller 48, the water level sensor 40, the light sensor 38 and the UV LED 42.

In the solar cell mode, the solar panel 53 is electrically connected to the solar charger 59 through the SPDT switch, which is electrically disconnected from the AC/DC adapter module 60.

Specifically, the user electrically disconnects the AC/DC adapter module 60 from the AC power grid 61, and the AC/DC adapter module 60 does not receive any AC voltage from the AC power grid 61. The user also places the SPDT switch in a second position with its second input terminal connected to its output terminal and its first input terminal not connected to its output terminal. Then, the solar cell panel 53 is electrically connected to the second input terminal of the SPDT switch, to the output terminal of the SPDT switch, and to the solar charger 59. The solar panel 53 then receives solar radiation and converts the solar radiation into electrical energy for transmission to the second input terminal, the output terminal and the solar charger 59. The transferred electrical energy is then used to charge the battery 62.

In one implementation, the AC/DC adapter module 60 is rated for 4 amps (A) and is adapted to provide an output DC voltage of 12 volts (V) to the solar charger 59.

Fig. 5 shows a flow chart 100 of a method for operating the improved mosquito eradication device 1.

The method comprises a step 103 of collecting and storing rain water in the container 22.

In step 110, the mosquito eradication device 1 is then placed in either the AC/DC adapter mode or the solar cell mode.

In the AC/DC adapter mode, the light sensor 38 detects the absence of light for an expected period and then sends a nighttime detection signal to the microcontroller 48. In a next step 115, the microcontroller 48 then energizes the UV LED 42 overnight to emit UV light in the container 22 to attract the female mosquitoes.

The water level sensor 40 then measures the water level in the container 22 and then sends the water level measurement to the microcontroller 48 in step 120.

In step 125, the microcontroller 48 then receives the measured value of the water level, once a day, and then determines the duration of the transmission of the ultrasonic waves based on the received measured value of the water level.

In a subsequent step 128, the microcontroller 48 activates the ultrasound generating device 43 for a determined time duration in order to emit ultrasound.

During the day, the light sensor 38 detects the presence of light for a predetermined period and sends a day detection signal to the microcontroller 48 to deactivate the UV LEDs 42.

In the solar cell mode, the light sensor 38 detects the absence of light for a predetermined period and then sends a nighttime detection signal to the microcontroller 48. In a next step 130, the microcontroller 48 then energizes the UV LEDs 42 for several hours to emit UV light, and then enters a sleep state to conserve energy.

The microcontroller 48 has a timer for waking up the microprocessor 48 from the sleep state to the active state after a first predetermined period, e.g. one week. Microcontroller 48 may also be restored to an operational state by signals from

sensors

38 and 40.

Step 130 is repeated every night until the timer reaches the end of the first predetermined period.

After that, the water level sensor 40 measures the water level and then transmits the measured value of the water level to the microcontroller 48 in step 133.

Subsequently, in step 136, the microcontroller 48 determines the duration of the ultrasonic wave transmission based on the received water level measurement.

The microcontroller 48 then activates the ultrasound generating means 43 for a determined duration to emit ultrasound. Then, in a subsequent step 139, the microcontroller 48 enters the sleep state again.

In one embodiment, the improved mosquito eradication device 1 also includes an attachment mechanism for mounting the mosquito killer 10 to the pole. An example of a connection mechanism is shown in fig. 6.

Different implementations of the ultrasonic transducer 47 are possible.

Instead of the ultrasonic transducer 47 being attached to the bottom of the container 22, the ultrasonic transducer 47 may be located below or near the bottom of the container 22, or inside the container 22, near the bottom of the container 22.

In a specific embodiment, the SPDT switch is replaced by a switching device. The switching device is configured to detect a voltage from the AC/DC adapter module 60 and automatically switch or place the mosquito killer 10 in the AC/DC adapter mode or the solar cell mode according to the detected voltage. In particular, if a predetermined voltage is detected, the switching device places the mosquito killer 10 in the AC/DC adapter mode. If the predetermined voltage is not detected, the switching device places the mosquito killer 10 in the solar cell mode.

The improved mosquito eradication device 1 provides a number of benefits.

The mosquito eradication device 1 is capable of effectively attracting, killing or destroying mosquitoes (when they are in the larval stage of their life cycle). The mosquito eradication device 1 may also be carried with a self-sustaining solar panel. This makes the mosquito eradication device 1 easy to deploy in remote areas where it is inconvenient to use an AC power grid.
