A mouse catching box comprises a box body (10), a lifting platform (20), and a control assembly (40). The box body (10) is provided with a trap opening (102) and a recovery opening (104). The lifting platform (20) is disposed at the bottom of the box body (10), and a mouse catching platform (30) parallel to the lifting platform (20) is disposed above the lifting platform (20). The control assembly (40) is disposed on the box body (10), and comprises a voltage measurement module (402), a controller (404), a high-voltage transformer (406), and a power grid (408). The voltage measurement module (402) transmits a triggering signal of the power grid (408) to the controller (404), and the controller (404) controls the high-voltage transformer (406) to supply power to the power grid (408). The power grid (408) comprises a positive power grid line (302) and a negative power grid line (304). The negative power grid line (304) in disconnection is divided into three segments connected respectively to a negative electrode of the high-voltage transformer (406). When a mouse connects the middle segment of the negative power grid line (304) to the positive power grid line (302), a triggering signal is generated. The mouse catching box has the following advantages: the power grid is densely arranged and the whole grid outputs a high voltage, thereby improving the efficiency for killing mice; the automatic return design of the mouse catching box makes the device automatically resets after the killing, and the mouse catching box can be continuously used to improve the long lasting effect.
A: A new multi-functional mosquito and fly killer lamp, comprising a lamp holder (1). A lower side of the lamp holder (1) is provided with a lamp body main body (4). An upper side of the lamp body main body (4) is provided with a driving controller (2). A right side of the driving controller (2) is provided with an odor mosquito and fly trapping box (3). A lower side of the lamp body main body (4) is provided with a mosquito and fly trapping luminous member (5). A lower side of the mosquito and fly trapping luminous member (5) is provided with a first high-voltage grid (6) and a second high-voltage grid (12). A lower side of the second high-voltage grid (12) is provided with a first illuminating luminous member (7). Mosquitoes and flies can be remotely trapped by adding a mosquito trapping agent with a lactic acid odor inside the odor mosquito and fly trapping box (3), thereby expanding the usable area. After being attracted and coming into contact with the first high-voltage grid (6) or the second high-voltage grid (12), the mosquitoes and flies can be killed. The first illuminating luminous member (7) and a second illuminating luminous member (10) are provided with LED beads. The new multi-functional mosquito and fly killer lamp has plentiful functions and can play a role in illumination.
B: A mousetrap capable of capturing multiple mice. The mousetrap comprises an upper box body (10), a lower box body (20), and a mouse storage box (30). The lower box body (20) is provided with at least a mouse intake step (21). A tail end of the mouse intake step (21) is horizontally provided with a high-voltage electric board (40). The mouse storage box (30) is arranged below the high-voltage electric board (40). A driving motor (50) is arranged in the lower box body (20), and a driving shaft of the driving motor (50) is sleeved with a driving gear (51). A rack (41) meshing with the driving gear (51) is fixed on the lower surface of the high-voltage electric board (40), so that the high-voltage electric board (40) is driven by the driving gear (51) to translate. A first baffle (11) is vertically arranged in the upper box body (10) on one side of the high-voltage electric board (40), and the first baffle (11) is used to block a mouse body when the high-voltage electric board (40) is translated, such that the mouse body falls into the mouse storage box (30). The mousetrap has an ingenious structure and a high space utilization rate.
C: Disclosed is a safe and energy-saving mosquito killing lamp, comprising a lamp holder (1), a shell (2) connected to the lamp holder (1), and a connecting base (3) connected to the shell (2). A first cavity is formed between the shell (2) and the connecting base (3). The connecting base (3) comprises a tapered portion extending into the first cavity, and a lamp post (11) arranged on the tapered portion. A mosquito trapping light source (15) is arranged on an outer surface of the lamp post (11). A mosquito killer (12) is arranged on the periphery of the mosquito trapping light source (15). The mosquito killer (12) is fixed inside the shell (2). The mosquito killer (12) comprises a positive electric net (1201) and a negative electric net (1202). The positive electric net (1201) and the negative electric net (1202) encircle each other and are not connected to each other. By means of arranging two electric nets, the safety performance of the mosquito killing lamp is improved. Since people cannot touch the inner electric net, the risk of electrical injuries due to accidentally touching the electric net can be avoided. By arranging the mosquito trapping light source (15) around the outer surface of the lamp post (11), the effect of efficiently trapping and killing mosquitoes at 360 degrees and the effect of energy conservation and environmental protection are achieved.
