Description

Technical Field

[0001] The utility model relates to the technical field of animal killing, in particular to a rodent killing device. Background Art

[0002] The representative of common rodents in daily life is the mouse. There are many types of devices for catching and killing mice, such as sticky mouse boards, mousetraps, mouse cages and box-type mousetraps, among which the box-type mousetraps have better catching and killing effects. For example, a Chinese utility model patent "A Rodent Catching Device" with application number CN202122616809.5 (publication number CN216164742U) discloses such a catching and killing device, which includes a box body, and the box body is provided with an entrance for rodents to enter the chamber. The bottom of the chamber is provided with discharge plates A and B connected to power supply ends with different voltages. When the mouse enters the chamber and crosses the discharge plates A and B, the control circuit will output a high voltage to knock the mouse down.

[0003] However, the discharge plates A and B in the chamber are arranged adjacent to each other, and the walking path of mice is usually complicated. Only when mice walk along a specific path can they cross the discharge plates A and B. Therefore, further improvements need to be made to the rodent killing device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a rodent killing device with a high killing success rate in view of the above-mentioned existing technical status.

[0005] The utility model solves the above technical problems by adopting the following technical solutions: the rodent killing device comprises:

[0006] A box body, the interior of which is hollow to form a chamber, and a side wall of the box body is provided with an entrance for rodents to enter the chamber;

[0007] At least two discharge plates connected to power supply terminals with different voltages and arranged at the bottom of the chamber;

[0008] A control circuit board is arranged on the box body, and the control circuit board is connected to the power supply end of the discharge board;

[0009] a sensor connected to the control circuit board, the sensor detecting rodents entering the chamber and transmitting a detection signal to the control circuit board;

[0010] The characteristic is that the discharge plate comprises at least two discharge sheets arranged at intervals and a base connecting the discharge sheets, the discharge sheets of adjacent discharge plates are arranged alternately, and an insulating gap is formed between adjacent discharge plates.

[0011] In order to simplify the assembly steps, preferably, the discharge plate is an integrated structure, and the discharge plate is composed of the base and the discharge sheet extending from the base. The discharge sheet is formed by extending from the base, and the base connects the discharge sheets together to form an integrated structure, which simplifies the assembly steps, and the arrangement can be completed by only staggering the discharge sheets of each discharge plate.

[0012] For the convenience of arrangement, preferably, the base or the discharge sheet is connected to the power supply end, wherein the entire discharge plate can be directly connected to the power supply through the base, or the discharge sheet can be connected to the power supply.

[0013] In order to increase the probability of rodents stepping on different discharge plates with both feet at the same time, it is preferred that the length of the discharge sheet is 2 to 6 times the width of the base. If the discharge sheet is too short compared to the length of the base, the killing efficiency will be insufficient, and if the discharge sheet is too long compared to the length of the base, the overall strength of the discharge plate will be insufficient. The length of the discharge sheet is designed to be longer than the width of the base, and the discharge sheets of adjacent discharge plates are staggered. It is easier for rodents to step on different discharge plates with both feet when they crawl or jump forward and backward, left and right, or diagonally, thereby increasing the chance of killing.

[0014] For the convenience of production, preferably, the shapes of the discharge sheets are the same, wherein the shapes of the discharge sheets are the same, which can facilitate mass production and improve production efficiency.

[0015] For the convenience of processing, the discharge sheet is preferably in the shape of a long strip, wherein the discharge sheet in the shape of a long strip is more convenient to be cut by machine than other complex shapes.

[0016] Preferably, the extension direction of the discharge sheet is parallel to the length direction of the chamber. When the discharge sheet is extended along the length direction of the chamber, the corresponding entrances need to be arranged on the side walls at both ends of the box body, and the probability of rodents entering through the entrances and being killed will increase.

[0017] Preferably, the extension direction of the discharge sheet is perpendicular to the length direction of the chamber. When the discharge sheet is extended perpendicular to the length direction of the chamber, the corresponding entrance needs to be set on the side wall of the box in the front and rear directions, and the probability of rodents entering through the entrance and being killed will increase.

[0018] In order to improve space utilization, preferably, the chamber includes a first chamber and a second chamber, and at least one group of discharge plates are provided in each of the first chamber and the second chamber, and each group of discharge plates includes a first discharge plate and a second discharge plate connected to different power supply voltages. The first chamber and the second chamber can kill rodents independently, and when a rodent is killed in the first chamber, there is still space in the second chamber for killing.

[0019] In order to facilitate rodents to enter the chamber, it is preferred that the entrances are arranged at both ends of the box, including a first entrance and a second entrance, the first entrance is connected to the first chamber, the second entrance is connected to the second chamber, and a bait area for placing bait is formed between the first chamber and the second chamber. Among them, rodents can enter the chamber from the first entrance or the second entrance, which increases the probability of rodents being killed. The bait is set in the bait area of ​​the chamber, and the smell of the bait can be emitted through the entrances on both sides of the chamber. The infrared sensor is set upstream of the bait area, which can detect and kill rodents before they reach the bait area, avoiding waste of bait.

[0020] Compared with the prior art, the utility model has the following advantages: the utility model arranges two discharge plates connected with different voltages adjacent to each other in the first chamber and the second chamber of the box body; the discharge plates include discharge sheets arranged at intervals and a base connecting the discharge sheets; the discharge sheets of adjacent discharge plates are arranged alternately, and rodents entering the chamber from the entrance can more easily step on two adjacent discharge plates when crawling along a conventional path, thereby increasing the success rate of capture and killing.

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] Example 1

[0028] like Figures 1 to 4 As shown, the rodent killing device in this embodiment includes a box body with a hollow interior forming a chamber 1, and an entrance 2 for rodents to enter the chamber 1 is arranged on the side wall of the box body; and four discharge plates 3 are arranged at the bottom of the chamber 1 and arranged at intervals, and two adjacent discharge plates 3 are connected to power supply ends with different voltages. The discharge plate 3 includes two discharge sheets 34 arranged at intervals and a base 33 connecting the discharge sheets 34. The discharge sheets 34 of adjacent discharge plates 3 are arranged in an interlaced manner, and an insulating gap is formed between adjacent discharge plates 3. It also includes a control circuit board arranged on the box body and connected to the power supply end of the discharge plate 3. The chamber 1 also includes a sensor connected to the control circuit board, which can detect rodents entering the chamber 1 and transmit the detection signal to the control circuit board.

[0029] refer to Figure 2 The discharge plate 3 can adopt an integrated or split structure. When the split structure is adopted, each independent discharge sheet 34 needs to be fixed to the base 33 by welding or other methods during the assembly process. In order to simplify the assembly steps, the preferred discharge plate 3 in this embodiment is an integrated structure. The discharge plate 3 is composed of a base 33 and discharge sheets 34 extending from the base 33, which simplifies the assembly steps. The arrangement can be completed by staggering the discharge sheets 34 of each discharge plate 3. The base 33 and each discharge sheet 34 on the discharge plate 3 are both provided with an interface connected to the power supply end. The entire discharge plate 3 can be directly connected to the power supply through the base 33, or the discharge sheet 34 can be connected to the power supply. In this embodiment, it is preferred to connect the base 33 to the power supply end.

[0030] refer to Figure 2 The length of the discharge sheet 34 is 2 to 6 times the width of the base 33. If the discharge sheet 34 is too short compared to the base 33, the killing efficiency will be insufficient. If the discharge sheet 34 is too long compared to the base 33, the overall strength of the discharge plate 34 will be insufficient. Considering the strength of the discharge plate 3 and the killing rate of rodents, the preferred length of the discharge sheet 34 in this embodiment is 3 times the width of the base 33. The length of the discharge sheet 34 is designed to be longer than the width of the base 33. It is easier for rodents to step on two discharge plates 3 with both feet at the same time when walking or even jumping in any direction, thereby increasing the probability of rodents being killed.

[0031] refer to Figure 2, each discharge sheet 34 has the same shape, which allows the discharge sheet 34 to be mass-produced, thereby improving production efficiency. The discharge sheet 34 can be designed in a variety of shapes, such as a triangle or a long strip, etc. In this embodiment, a rectangular shape is preferred for convenient cutting during machine processing. The rectangular-shaped discharge sheet 34 has a regular outline and convenient cutting steps. The extension direction of the discharge sheet 34 is parallel to the length direction of the chamber 1, and the corresponding entrance 2 is set on the side walls at both ends of the box body. At this time, the probability of rodents entering from the entrance 2 and being killed will increase.

[0032] refer to Figure 2 and Figure 3 The chamber 1 includes a first chamber 11 and a second chamber 12. At least one set of discharge plates 3 is provided in each of the first chamber 11 and the second chamber 12. In this embodiment, it is preferred that a set of discharge plates 3 is provided in each chamber 1. Each set of discharge plates 3 includes a first discharge plate 31 and a second discharge plate 32 connected to different power supply voltages. The first chamber 11 and the second chamber 12 can kill rodents independently. When a rodent is killed in the first chamber 11, there is still space in the second chamber 12 for killing. The entrance 2 is provided at both ends of the box body, including a first entrance 21 and a second entrance 22. The first entrance 21 is connected to the first chamber 11, and the second entrance 22 is connected to the second chamber 12. A bait area 13 for placing bait is formed between the first chamber 11 and the second chamber 12. Rodents can enter the chamber 1 from the first entrance 21 or from the second entrance 22, thereby increasing the probability of rodents being killed. The bait is set in the bait area 13 of the chamber 1, and the smell of the bait can be emitted through the entrances 2 on both sides of the chamber 1. The infrared sensor is set upstream of the bait area 13, which can detect and kill rodents before they reach the bait area 13, avoiding waste of bait.

[0033] There are two ways to wake up the killing device. One is to wake up the control circuit board by detecting the impedance change between two adjacent discharge plates 3, and the other is to detect rodents entering the chamber 1 through sensors. The wake-up module in the killing device is connected to the control circuit board. The wake-up module can detect the impedance change signal between two adjacent discharge plates 3 and transmit the signal to the control circuit board, thereby waking up the control circuit board from a low-power state. The control circuit is in a low-power state in standby mode. When a rodent straddles two adjacent discharge plates 3, the wake-up module can detect the impedance change between the two discharge plates 3 and transmit the signal to the control circuit board. The control circuit board enters the working mode to power the discharge plate 3 to kill the rodent. The wake-up module can refer to the "A Mousetrap" disclosed in the Chinese utility model patent with application number CN201921527876.6 (announcement number CN211185601U).

[0034] The specific working process of the killing device is as follows: This embodiment takes the first chamber 11 as an example for description. Turn on the power switch and observe the indicator light on the cover. If the red light flashes, the voltage is abnormal and the battery needs to be replaced. If the green light is displayed, it is normal. Before use, it is necessary to check whether there is any foreign object blocking the infrared sensor in the chamber 1. If there is, it needs to be cleaned. Turn off the infrared sensor, turn on the sensor, the wake-up module enters the working state, and the control circuit is in a low-power standby state. When a rodent enters the first chamber 11 from the first entrance 21, the sensor near the entrance 2 can detect the entry of the mouse, or the sensor and the wake-up module detect the entry of the mouse at the same time, and send a signal to the control circuit board. The control circuit on the control circuit board is awakened from the low-power standby state, exits the standby mode, and starts the infrared sensor. When the light beam emitted by the infrared transmitter is blocked, it is determined that a rodent has entered the chamber 1. The discharge plate 3 continuously outputs high voltage for 90 to 300 seconds to kill the mouse. At this time, the indicator light is displayed in green and flashes once every second to remind the user to clean up the mouse. If the light beam from the infrared transmitter is not blocked and the detection time exceeds the set time, the infrared sensor will be returned to re-detect. The working process of the second chamber 12 is the same as that of the first chamber 11. When a rodent is killed in the first chamber 11, the second chamber 12 can continue to work.

[0035] Example 2

[0036] The difference between this embodiment and the first embodiment is: the location of the box inlet 2 and the arrangement of the discharge plate 3. Figure 1 and Figure 4 The first inlet 21 and the second inlet 22 are arranged on the side wall in the front-back direction, the first inlet 21 is connected to the first chamber 11, the second inlet 22 is connected to the second chamber 12, and the extension direction of the discharge sheet 34 is perpendicular to the length direction of the chamber 1. The rest of the structure of the killing device in this embodiment is the same as that of the first embodiment.
