Description

Invention Patent Report for "Mosquito larvae exterminator".

Field of the Invention This document belongs to the field of traps, namely traps for killing mosquito larvae.

Background of the Invention Several viruses are transmitted by mosquitoes and other arthropods, called arboviruses. More than 100 species of arboviruses that cause infections in humans or animals have been identified. Mankind has always suffered from mosquito-borne diseases such as malaria, dengue, filariasis, leishmaniasis. More recently epidemics of dengue, zika and chikungunya have caused serious public health problems in tropical and subtropical countries. There are several proposals for prior art mosquito traps for the elimination of these vectors. Existing devices are diverse and usually use chemicals, electricity, fictitious breeding and others.

State of the Art PI0203907-9 discloses a trap and method for capturing Aedes aegypti, Aedes albopictus, Anopheles sp and Culex mosquitoes. The device and method allow the monitoring, detection and control of these disease-transmitting insects. It consists of surfaces of different colors and geometries which also have a glue so that these vectors stick to the surface of the device.

[004] French document FR2897509 discloses a device having a container filled with cold water, wherein the receiver is opaque and dark in color to attract Aedes aegypti mosquitoes. A cover system preferably has a height of 20 centimeters, and covers the entire length and half the width of the container to provide shelter for mosquitoes. Plants such as cabbage and water hyacinth are used to ensure oxygenation of the device.

[005] US6688035 discloses a method and apparatus consisting of the production of carbon dioxide and water vapor in conjunction with an insect attraction system for the purpose of eliminating them. The invention describes an economical and convenient device for producing an insect attraction system using paraffin combustion.

PCT WO2014167553 discloses a trap designed to capture the Aedes aegypti mosquito. Said retainer uses visual and chemical stimuli as an attraction mechanism, visual stimuli are provided by two contrasting colors: red on the trap body and black on the trap entrance. The trap consists of a pyramidal trunk body with a square base made of translucent polymethyl methacrylate, which has an opening in the apical lateral zone, where the entrance to the mosquitoes is located. In general, the trap of the present invention comprises a plurality of elements that enhance the capture of the mosquito considering its internal characteristics.

SUMMARY OF THE INVENTION The screen device consists of a mosquito larvae exterminator comprising a reservoir (1) for conditioning gravity-filled water from a container (2), wherein said device further has a timer (3). ) which activates an electrical resistor (4) in contact with the container (2), which promotes the heating of the water of said container (2) to its boiling point in regular periods smaller than the larval hatching cycle.

Said mosquito larvae exterminator device also has a lid (5) capable of being closed if the timer (3) reaches the moment of activating the resistor (4) and the controller circuit identifies that there is no electric power available in the the water boiling mains, the battery powered timer (3) being preferably of the rechargeable type coupled to the controller circuit which activates a relay (9) which activates the lid (5) to close the container (2).

The mosquito larvae exterminator device further comprises auxiliary structures such as a float for indicating the water level of the reservoir (1) and a grid (6) in the container (2).

[010] In addition the mosquito larvae exterminator device may have structures such as female sockets (7) for connecting other devices and a led lamp (8) at the top of the device.

The mosquito larvae exterminator device still has structures such as a float arranged on the upper part of the reservoir (1) to control the water level of this structure, a second float (11) coupled to the container (2) for control. water level and a flavoring tower (10) disposed on the side of the reservoir (1).

DETAILED DESCRIPTION OF THE INVENTION The screen device is intended to combat the transmitting mosquito of Dengue, Zika and Chikungunya, ie preferably the Aedes aegypti mosquitoes.

[019] The device also has the benefit of being environmentally friendly as it does not use chemical methods to achieve its purpose. Thus, it does not promote environmental contamination, as some other existing and commercialized methods use poison, bringing possible risks to human health, environmental contamination and groundwater.

[020] The device acts as a trap by attracting the mosquito to its breeding ground, ie regions with clean and standing water. Once installed the device should be replenished within a few months.

[021] The device consists of a water reservoir (1). In addition, it has the option of supplying water directly through the tap. The device also has a container (2), separate from the reservoir (1), where the water with the mosquito larvae will be boiled using an electric resistor (4). A float is used to measure the water level as well as a timer (3) preferably one, two, three up to four days or 24, 48, 62 and 84 hours is used to regulate trap activity periods according to the hatching cycle of the mosquito larvae of interest. That is, you regulate the period that the water will boil according to the mosquito species you want to kill the larvae. In these periods when the trap will be exposed the mosquito will lay its eggs and after the time set by the person through the timer (3) the water will boil for a period of 12 to 20 minutes. In the case of the Aedes Aegypti mosquito it is known that the time does not exceed four days, since the period of the larva's cycle until its transformation into a mosquito is five days. According to this dynamics of operation and being the device placed to operate repeatedly, the number of transmitting mosquitoes can be reduced by interfering with its reproduction cycle.

[022] The device also has two floats, one arranged in the reservoir (1) for controlling the water level of this first structure receiving water and a second float (10) coupled to the container (2) for controlling the level of water. water that will be boiled.

[023] Two devices coupled to the invention increase the operating safety of the invention: - a lid (5) capable of closing if the timer (3) reaches the user-specified time zero, indicating that there is no electric power to boil the Water. Thus, the timer (3) has its own back-up electricity provided by a rechargeable battery attached to the device to activate a relay (9) which pushes the lid (5) closing the container (2) if necessary. -a grid (6) will be placed over the heating container (2) to prevent birds from bathing or drinking water from the container (2).

[024] In addition there is the possibility of coupling a lamp (8) "led" on the top of the device as well as a flavor (11) arranged in the reservoir (1) to help identify the time of boiling water concurrently with the function of perfuming the environment.
