(2) background technique:

Existing kill mosquito mode is varied, as use the chemical spray agent, or heating, solid-state, the liquid mosquito-killing insence of burning, or combine with electric grid with sound wave or light and to trap electric shock, because spray and mosquito-repellent incense be the meeting contaminated air in kill mosquito, continue the use meeting for a long time human body is impacted or injures; And when traping mosquito with sound wave or light source, because outdoor mosquito and insect lured by it also, and ground auger is gone into indoorly by every means, and the mosquito in the inlet chamber not necessarily all flies into electric grid, therefore caused kill mosquito on one side, Yi Bian attract the phenomenon of mosquito.

For not only easy but also effective kill mosquito, existing a lot of people masters' imaginations are installed mosquito killing device on electric fan, under the prerequisite that does not influence the function of electric fan own, increase the kill mosquito function.As application number is 92246129.5, and name is called the Chinese patent of " kill mosquito fan ", is on the fan back cover screen cloth to be installed, and is equipped with on screen cloth and pulls out bar.This device is to utilize negative pressure that mosquito is adsorbed onto on the screen cloth, rotates then and pulls out bar, with pulling out bar mosquito is killed.Because above-mentioned patent needs to adorn a rotating bar that pulls out on screen cloth, therefore must increase by one and can drive the device that pulls out the bar rotation, must change the structure of existing fan like this.Therefore for manufacturer, for implementing this patent die sinking tool again, and change production technology, for the user, must buy electric fan again and maybe will have the electric fan repacking, these reasons have limited the enforcement of above-mentioned patent; And the bar that pulls out that is loaded on the screen cloth fractures easily, can push the effect of killing mosquito and will reach rotatable, and the manufacturing technique requirent that pulls out bar is also very high.

In order to utilize the fan kill mosquito, also have the multiple mode that mosquito killing device is installed on fan, but the parts that these devices comprise are more, as mosquito luring lamp, acoustic emission apparatus, perhaps other mosquito attracting and killing device, its complex structure, cost is higher, and a lot of optional features gather the effect that does not reach the accumulation of kill mosquito efficient, therefore, the enforcement rate is not high, but does not see fan or the mosquito killing device popularization and application of attaching on fan that mosquito killing device is housed so far.

(3) model utility content:

The utility model need change existing fan structure or himself complex structure at the mosquito killing device that has the kill mosquito fan now or be loaded on the fan, defectives such as the cumulative effects of multinomial function is not obvious, designed and a kind ofly need not change existing fan structure, can directly be installed on the existing fan, structure is very simple, with low cost, and effect exterminating mosquito well is installed on the kill mosquito fan guard on the fan.

The utility model kill mosquito fan guard, comprise screen cloth, the bearing support of supporting and fixed grit, with the fixed connection apparatus that whole kill mosquito fan guard is installed on the fan, different is: described bearing support has a size and conventional fan front shroud foundation ring or the corresponding foundation ring of fan panel inside casing that wind direction is regulated the blade face is housed; And the height of described kill mosquito fan guard 〉=60 millimeter.

Described bearing support is provided with equally distributed side support, and described side support is horn-like and outwards opens.

The subtended angle α of described side support is 20～60 degree.

The subtended angle α of described side support is 30 degree.

Also be equipped with on the described kill mosquito cover and lure the mosquito device.

This kill mosquito fan guard only changes the structure of fan front shroud, or substitute the front shroud of original fan guard or this novel kill mosquito fan guard is installed on the box fan that takes down the change of the wind blade with this novel kill mosquito fan guard, therefore can not increase the cost of manufacturer and increase Consumer's burden, for the family that has electric fan, this novel kill mosquito fan guard can directly be installed, and its installation is also very convenient.This kill mosquito fan guard can have been catched and killed indoor most mosquito under the situation that does not have additional other trap, therefore need not add the kill mosquito requirement that other device can reach general family for household type kill mosquito fan guard.

(4) description of drawings:

Fig. 1 is the orthographic projection direction structure schematic representation of the utility model exemplary embodiment;

Fig. 2 is the side-looking direction structure schematic representation of Fig. 1.

(5) embodiment:

When specifically implementing the utility model, as shown in Figure 1 and Figure 2, this kill mosquito fan guard includes screen cloth 1 and is used for fixing bearing support 2 with support screen, screen cloth 1 is fixed on the bearing support 2, bearing support 2 has a foundation ring 21 that is used to tighten up with 1 mouthful of fixed grit, on the foundation ring 21 or bearing support 2 other members be provided with and be convenient to screen cloth 1 and whole kill mosquito fan guard are installed in fixed connection apparatus on the fan; Because when mosquito is just arrived in the kill mosquito fan guard by negative-pressure adsorption, can struggle and disorderly fly everywhere, if the insufficient height of screen cloth 1, mosquito might escape out, therefore screen cloth 1 or the height h that is fixed with the fan guard that goes out of screen cloth 1 are greater than 60 millimeters, and in order to make the mosquito that is blown on the screen cloth 1 be difficult for flying out 1 mouthful of screen cloth, bearing support 2 preferred design become horn-like, make the mosquito difficulty of entering to come out easily; And the horn-like structure of front end broad also makes front end that the space of splendid attire mosquito is arranged, and makes the mosquito of being catched and killed be accumulated in the lower end of horn-like front end, and horn-like front end does not influence the air-out of fan yet.Reach above-mentioned effect, the subtended angle α of side support 22 should be greater than 15 degree on the bearing support 2.The size of subtended angle α is with the height h of screen cloth 1 decision, and when h was big, α can be less, and when h hour, α can be bigger.But because subtended angle is big more, then situation lower supporting frame 2 front ends highly identical are big more, and the size of front end exceeds the fan edge when too many, use inconvenient, and increased cost, therefore subtended angle effect exterminating mosquito when 15～60 spend can reach the requirement of general family, is preferably in 30 degree by the size of general electric fan.

When catching and killing open-air insect such as farmland with this device when needs, height of this fan guard and subtended angle all should enlarge, and can lamp source of attaching or sound source etc. lure the mosquito device on fan or fan guard, and mosquito is lured by the fan guard at a distance, adsorbs and catches and kills.
