Abstract

A device to trap and kill flying insects such as mosquitoes and flies. The device comprises: an upper housing 1 with electric motor; a connecting rod 3 coated with an adhesive attractant; a movable middle barrel 2 containing a reservoir of the attractant, a sponge-like block to apply the attractant to the rod, and a lower scraping cover; and a lower housing 4 for containing a liquid to drown the insects. The central rod connects the upper housing to the lower housing, and also acts as the axis for the middle barrel to slide vertically on. In use, the middle barrel is raised by the motor along the connecting rod, applying sticky attractant such as sugar syrup along the length of the rod or rods. The barrel is lowered by the motor, with the bottom edge scraping stuck insects from the rods, into the liquid container below, where the trapped insects are smothered.

Referring to Fig.19, the first lower cover 113 provides an opening 72 for avoiding the first and second drawstring 5, 6, a first through hole 71 for 10 connecting with the connecting rod 3, a boss with thread for mounting the actuator 14.

Referring to Fig.20, the diameter of the end portion of the connecting rod 3 for cooperating with the upper barrel 1 is greater than the diameter of the body of the connecting rod 3, the end portion cooperates with the boss of the first lower cover 113, the connecting rod 3 and the first lower cover 113 are fastened by washers 85 and nuts 84. The nut 84 is fastened after the fastening of the lower barrel 4 and the thread portion of the end portion of the connecting rod 3.

In the following, the work process of the device will be described.

Infuse water 7 into the lower barrel 4, the water level is about the 3/4 of the lower barrel 4. Water, which is easy to get and is cheap, is a preferential kind of liquid to smother mosquitoes and/or flies.

Put appropriate amount of sugar and a little water into the charge chamber 86. Sugar, which is easy to get and is cheap with respect to fruit juice or bee honey, is a preferential kind of inducer to entice mosquitoes or flies. Sugar melted by water gets into the agglutinate block 222 through the fourth through hole74, due to the respective movement of the agglutinate block 222 and the connecting rod 3, inducer in the agglutinate block 222 moves to 5 the connecting rod 3 so as to make the connecting rod 3 have a function of enticing mosquitoes and/or flies. Obviously, only sugar is put into the charge chamber 86, the water in the air can damp the sugar, the damped sugar slowly gets into the agglutinate block 222 through the fourth through hole 74, so put sugar together with water into the charge chamber 86 can make 10 sugar quickly get into the agglutinate block 222.

Referring to Fig.1 and Fig.2, the middle barrel 2 axially moves between the first position and the second position; at the first position, the lower-half of the connecting rod 3 is visible and the upper-half of the connecting rod 3 is covered by the middle barrel 2, at the second position, the bottom portion of the middle barrel 2 fits well with the bottom portion of the lower barrel 4, the lower-half of the connecting rod 3 is covered by the middle barrel 2, the upper-half of the connecting rod 3 is visible. The actuator 14 drives the internal barrel 22 and the external barrel 21 moving with respect to the connecting rod 3 (see Fig.3 to Fig.4).

The internal barrel 22 and the external barrel 21 connect to the actuator respectively with the first drawstring 5 and the second drawstring 6. When the first electric motor 141 of the actuator 14 rotates positively, the first drawstring 5 entwines around the first wire rewinding wheel 143 through the worm and gear so as to make the internal barrel 22 move up along the connecting rod 3 till the internal barrel 22 reaches the top portion of the middle barrel 2, the first electric motor 141 stops rotating, due to the non-reversible drive of the worm and gear, the internal barrel 22 located at the top portion of the middle barrel 2 do not move down even under the effect of gravity force. Equally, the second electric motor 142 of the actuator 14 rotates positively, the second drawstring 6 entwines around the second wire rewinding wheel 144 through the worm and gear so as to make the external barrel 21 move up along the connecting rod 3 till the external barrel 21 reaches the first position, the second electric motor 142 stops rotating, due to the non-reversible drive of the worm and gear, the external barrel 21 do not move down even under the effect of gravity force. The inducer within the agglutinate block 222 moves to connecting rod 3 as the up-and-down motion of the internal barrel 22, when the external barrel 21 is at the first position, the visible connecting rod 3 entices the mosquitoes and/or flies with the inducer on the external surface of the connecting rod 3 so as to gather them on the rod 3. When mosquitoes and/or flies on the rod reach a certain number, firstly, the second electric motor 142 rotates negatively, the second drawstring 6 is untied from the second wire rewinding wheel 144 through the worm and gear, with the help of gravity force, the external barrel 21 moves down as the second electric motor 142 rotating negatively, the second electric motor 142 stop rotating until the bottom portion of the external barrel 21 fit with the internal bottom of the lower barrel 4, at this moment, mosquitoes and/or flies are kept in the space formed by the third lower cover 225 of the internal barrel 22 and the water surface of the lower barrel 4. Secondly, the first electric motor 141 rotates negatively, the first drawstring 5 is untied from the first wire rewinding wheel 143 through the worm and gear, with the help of gravity force, the internal barrel 22 moves down as the first electric motor 141 rotating negatively, during the course of moving down, the third lower cover 225 strips mosquitoes and/or flies gathered on the rod 3, because the gaps between moving parts is less than the body size of mosquito or flies, the mosquitoes and/or flies stripped from the rod 3 can not escape from the device through the gaps. More mosquitoes and/or flies are stripped down as the internal barrel 22 continues moving down, some of them may drop on the liquid surface of the lower barrel 4, when the bottom portion of the internal barrel 22 moves bellow the liquid surface, all the mosquitoes and/or flies gathered on the rod 3 are stripped down and are pressed bellow the liquid surface, they will be drown under liquid as there is no oxygen supply for breath, when the external barrel 21 moves to the second position, the first electric motor 141 stops rotating.

Because the bottom portion of the external barrel 21 fits well with the is internal bottom of the lower barrel 4, the mosquitoes and/or flies pressed under the water are kept in the external barrel 21, if the bottom portion of the external barrel 21 do not fit with the internal bottom of the lower barrel 4 resulted in a gap leaving between them, it may cause that the mosquitoes and/or flies under water escape from the device through the gap, so the zo efficiency of device is reduced. The order of movement of the internal barrel 22 and the external barrel 21 can be successively seen from Fig.14,13,12. Ten minutes later, the first electric motor 141 rotates positively to make the internal barrel 22 move up, the water left in the internal barrel 22 is quickly drained off through the sixth through hole 76 arranged to the third lower zs cover 225 so as to reduce the electric motor burden after the internal barrel 22 moves out of water, the first electric motor 141 stops rotating when the internal barrel 22 moves to the top portion of the external barrel 21.

The second electric motor 142 starts rotating positively so as to make the external barrel 21 move up till the external barrel 21 is at the first position, then the connecting rod 3 attached with inducer is visible to entice the next group of mosquitoes and/or flies.

Obviously, changing the kinds of inducer can entice different kinds of insects, inducer includes opposite sex hormone.

According to the invention, non-toxic inducer entices mosquitoes and/or 10 flies to gather on the rod 3, then a mechanical manner is taken to smother them, the killing course do not cause secondary pollution or threat to health.
