The environmental protection mosquito trap
Technical field:
The utility model relates to the mosquito trap field, refers in particular to a kind of environmental protection mosquito trap.
Background technology:
Mosquito is one of " four pests ", and its existence and appearance bring very big trouble to people.Mosquito can be propagated various diseases, as malaria, yellow fever, dengue fever, encephalitis or the like.Because mosquito is very little, very difficult seizure obtains, spray and can pollute room air with medicine, see Fig. 1, occurred a kind of electric mosquito trap now on the market, it is to be made of support 01, the bottle 02 that fills chemical agent, support 01 top offers a through hole, the bottleneck of bottle 02 is placed in the through hole of support 01, and the inwall of through hole is fixed with sheet metal, and sheet metal is connected with plug.Utilize the fragrance of the chemical agent in the bottle 02 to attract mosquito, when treating that mosquito flies to bottle mouth position, electrocuted thereby brush up against the sheet metal of having switched on.This class mosquito trap has a lot of weak points, and for example, it need use chemical agent, and this is bad to health; Generally speaking, sheet metal voltage can too high (otherwise will not damage support 01), so only can be by corona when mosquito brushes up against sheet metal; This mosquito trap is not used for holding the gatherer by the mosquito of corona; Do not have indicator lamp on it, when using this type of mosquito trap night, may occur owing to the user meets this mosquito trap because of carelessness, even the situation of getting an electric shock.
Summary of the invention:
The purpose of this utility model is the environmental protection mosquito trap easy to use, safe that a kind of environmental protection is provided at the deficiencies in the prior art.
For achieving the above object, the utility model adopts following technical scheme: it includes overhead guard, airflow duct, and the side of airflow duct has a breach, is provided with LED in this gap edge place, the airflow duct below is provided with a fan, and the below of fan is provided with a gatherer.
One photo resistance is installed on the described overhead guard.
On the described air conducting inside pipe wall heating wire is installed.
Described airflow duct underside connects a casing, and fan, gatherer all are fixed in the casing.
The utility model utilizes sensitization (particularly purple light) of mosquito and the instinct that the temperature close with human body hunts for one's prey, use purple LED (light emitting diode) sends the purple light wavelength and the electrothermal wire heating attracts mosquito, the negative pressure that produces when utilizing fan to rotate simultaneously sucks mosquito in the mosquito trap, and drop in the gatherer of fan below, mosquito is died of hunger in gatherer.The utility model also is provided with the effect of photo resistance to realize starting and closing automatically automatically.The utlity model has environmental protection, safety, characteristics such as easy to use.

Embodiment:
See accompanying drawing 2-5, the utility model comprises: overhead guard 1, airflow duct 2, overhead guard 1 can be arbitrary shapes, and airflow duct 2 is an infundibulate.Have a breach 21 in the side of airflow duct 2, be provided with most LED22 in these breach 21 edges, the utility model adopts and can send the relatively LED of responsive purple light of mosquito.
Be provided with a fan 3 in airflow duct 2 belows, the direction of fan 3 blowing is basipetal, and the below of fan 3 is provided with a gatherer 4 that is used for holding mosquito.Because the wind of fan 3 outwards blows through gatherer 4, so most very little air vents are arranged on the gatherer 4, it is also passable that perhaps gatherer 4 directly adopts the sack with grid.
On airflow duct 2 inwalls heating wire 23 is installed.Certainly, airflow duct 2 adopts heat-barrier material to make.
Airflow duct 2 underside connect a casing 24, and fan 3, gatherer 4 all are fixed in the casing 24.Casing 24 outsides are equipped with gauge tap, and circuit board also is installed in the casing 24.
Connect power supply, by switch LED22, heating wire 23 and fan 3 are started, LED22 sends the light of purple, heating wire 23 heats gradually, ambient air is become to warm up, fan 3 blows air from top to bottom, and is less and one downward attraction arranged at the pressure at breach 21 places of airflow duct 2.
Mosquito flies nearly airflow duct 2 gradually, when it flies to breach 21 places, is easy to down be inhaled by swiftly flowing air, passes airflow duct 2 and falls into gatherer 4, thereby died of hunger in gatherer 4.
One photo resistance 11 is installed on overhead guard 1, and the work by photo resistance 11 is closed mosquito trap daytime automatically, and start night automatically, without manual operation.
The casing 24 inner circuit boards of installing can be controlled when heating wire 23 temperature are raised to certain limit and stop, and reach when temperature drops to certain limit and restart.Also be provided with a microswitch 25 between gatherer 4 and heating wire 23, the fan 3, when taking out gatherer 4, microswitch 25 disconnects, and fan 3, heating wire 23 quit work, and when gatherer 4 playback, works on again.
Owing to be provided with LED22, just can because of see do not run into mosquito trap when using the utility model night.The utility model effect simple in structure, easy to use, that catch mosquito is comparatively remarkable, and owing to do not adopt chemicals, has the characteristics of environmental protection, safety.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
