DETAILED DESCRIPTION

[0016] The present invention is described in detail below in conjunction with specific embodiments.

[0017] like Figure 1-3 As shown, this embodiment includes a box body 101 made of insulating material, a box door 102 is provided on the box body 101 , and an electric shock component 103 and a bait 104 are provided inside the box body 101 .

[0018] The box body 101 is also provided with a door opening maintaining component for maintaining the box door 102 in an open state, a bait detection module 230 for detecting whether the mouse has eaten the bait 104 and controlling the door opening maintaining component, a door closing maintaining component for maintaining the box door 102 in a tightly closed state, a door closing detection module for controlling the door closing maintaining component and controlling the electric shock component 103, and a power supply module for supplying power to the electric shock component 103 as well as to the door opening maintaining component, the bait detection module 230, the door closing maintaining component and the door closing detection module.

[0019] The mice lured into the box 101 and chewing the bait 104 will trigger the bait detection module 230. After the bait detection module 230 is triggered, the door opening maintenance component is disconnected to close the box door 102. After the box door 102 is closed, the door closing detection module is triggered. The door closing detection module controls the door closing maintenance component to close the box door 102 to prevent the mice from knocking the door open. At the same time, the door closing detection module energizes the control electric shock component 103 to electrocute the mice in the box 101.

[0020] The present invention can effectively capture mice and electrocute mice, is very convenient to use, and the electric shock process is completed in the insulated and closed box 101, which will not cause any impact on the human body and surrounding electric control equipment, and is very safe.

[0021] Preferably, the power module includes a first power group and a second power group, the first power group supplies power to the door opening maintenance component, the bait detection module 230, the door closing maintenance component and the door closing detection module, the second power group supplies power to the electric shock component 103, and the first power group and the second power group share the same power input terminal 201. Since the present invention mainly uses low-voltage weak electricity for control, but the electric shock component 103 requires high voltage electricity, this preferred solution divides the power module into a first power group for low-voltage control and a second power group for high-voltage electric shock, which can make the power system of this system more organized and avoid confusion in electricity use. In addition, the first power group and the second power group share a power input terminal 201, which makes the integration of the power system higher, and only one power connector is needed when using it, which is very convenient.

[0022] Further optimization is made, the power input end 201 is set to 220V AC, the power input end 201 of the first power supply group is connected to the first transformer 202 for voltage transformation, the secondary coil output end of the first transformer 202 is connected to the rectifier for AC to DC conversion, the output end of the rectifier is connected to the voltage stabilizer for voltage stabilization, and a filter is set between the rectifier and the voltage stabilizer for filtering, and the safe and stable voltage generated by the voltage stabilization is used to power the door opening maintenance component, the bait detection module 230, the door closing maintenance component and the door closing detection module. In addition, the power input end 201 of the second power supply group is connected to the second transformer 203, and the secondary coil input end of the second transformer 203 is used to power the electric shock component 103.

[0023] The above preferred configuration can well realize the division of the same input power supply into two parts, one of which outputs weak DC power and the other outputs high voltage power. Moreover, the preferred solution provides safe and stable power supply, thereby improving the power safety factor of the electric control system.

[0024] Preferably, the door opening maintenance component includes a first electromagnet 241 and a first iron block 242, the first electromagnet 241 is arranged on the door frame, the first iron block 242 is arranged on the hinged end of the box door 102, and the first electromagnet 241 can absorb the first iron block 242 to keep the box door 102 in an open state. The bait detection module 230 controls the on and off of the first electromagnet 241. The door closing maintenance component includes a second electromagnet 271 and a second iron block 272, the second electromagnet 271 is arranged on the door frame, and the second iron block 272 is arranged on the box door 102, preferably on the handle end of the box door 102, and the second electromagnet 271 can absorb the second iron block 272 to keep the box door 102 in a closed state. The electric shock assembly 103 includes two metal pieces 280 parallel to each other and a normally open electromagnetic relay 251. The distance between the two metal pieces 280 is slightly less than the height of an ordinary mouse. The secondary coil of the second transformer 203 supplies power to the metal piece 280, and the normally open electromagnetic relay contact 252 controls the on and off of the metal piece 280. The door closing detection module is a second contact switch 260. One contact of the second contact switch 260 is arranged on the box door 102, and the other contact is arranged on the door frame.

The electromagnet has a simple structure, is convenient and durable, and is very suitable for the present invention. The bait detection module 230 can directly use a button switch, and the mouse will press the button switch when gnawing the bait 104. The second contact switch 260 selected by the present invention directly uses the on-off of the contact to achieve control. Therefore, this preferred solution does not use any sensor electrical components, and directly uses the various on-offs of the circuit to achieve control. This saves costs on the one hand, and can also optimize the structure of the entire device, and it is not easy to be damaged and is durable.

[0026] Preferably, it also includes a door opening detection module, which controls the door opening maintenance component and the electric shock component 103, and the power module supplies power to the door opening detection module. The door opening detection module mainly serves to further improve the safety of the electric control system. When the door opening detection module detects that the box door 102 is open, it controls the electric shock component 103 to cut off the power. Therefore, when the box door 102 is opened, even if someone reaches out and touches the electric shock component 103, it will not cause an electric shock accident, thereby improving safety.

[0027] Further optimization is made, the door opening detection module includes a first contact switch 220 and a normally closed electromagnetic relay 211, one contact of the first contact switch 220 is arranged on the door frame, and the other contact is arranged at the hinged end of the box door 102. When the box door 102 is opened, the two ends of the first contact switch 220 are in contact, the first contact switch 220 controls the power on and off of the winding of the normally closed electromagnetic relay 211, and the normally closed electromagnetic relay contact 212 controls the power on and off of the electric shock component 103. This optimized design also uses the simple and effective method of electromagnet and contact switch to achieve the safety control of the electric shock component 103, and this setting is cleverly integrated into the above scheme to form a unified whole with the above scheme.
