Description

Technical Field

[0001] The invention relates to a mousetrap and also to a method for using the mousetrap. Background Art

[0002] Among the existing mouse catching devices, the most commonly used and effective method is to use high voltage electric shock to catch mice. The mousetrap using this method generally includes a mouse cage, and the bottom end surface of the mouse cage is paved with a discharge plate A and a discharge plate B. The discharge plate A and the discharge plate B are square plates with a small gap between them. The discharge plate B is located at the inner end. The mouse cage is provided with a power module, an LED light indicator module and a PCB board with an integrated control circuit. The power module, the LED light indicator module, the discharge plate A and the discharge plate B are all connected to the PCB board. When working, when the mouse enters the mouse cage and crosses between the discharge plate A and the discharge plate B, the mouse acts as a resistor in the circuit to connect the discharge plate A and the discharge plate B. The PCB board controls the discharge plate A and the discharge plate B to output a high voltage to knock the mouse down with a high voltage.

[0003] A mousetrap is disclosed in the US patent with the authorization announcement number US7757430B. A light beam sensor is added to the mousetrap. The transmitter and receiver of the light beam sensor generate a light beam signal in the gap between two discharge plates. When a mouse enters the mousetrap, the light beam signal is triggered, and then the two discharge plates are energized, thereby killing the mouse. However, in a mousetrap with this structure, if the mouse's feet are not distributed on the two discharge plates and the head triggers the light beam signal, the mousetrap may not necessarily kill the mouse. The discharge plates may be triggered by mistake, and the possibility of the mouse escaping is high. In addition, the mousetrap only uses a light beam signal to determine whether a mouse has entered, which may easily lead to the mistaken capture and killing of small pets at home. In addition, since the light beam sensor is always in the on state, it will cause a waste of electricity, especially for a battery-powered mousetrap, which will greatly reduce the standby time of the mousetrap. Summary of the invention

[0004] The first technical problem to be solved by the present invention is to provide a mousetrap which can reliably kill mice when the mice trigger the infrared sensor in view of the above-mentioned prior art.

[0005] The second technical problem to be solved by the present invention is to provide a mousetrap that can avoid accidental injury in view of the above-mentioned prior art.

[0006] The third technical problem to be solved by the present invention is to provide a mousetrap capable of reducing standby power consumption in view of the above-mentioned prior art.

[0007] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a mousetrap, comprising

[0008] A squirrel cage has a containing cavity inside and an entrance at the rear of the squirrel cage;

[0009] A control circuit board is arranged on the squirrel cage;

[0010] The discharge plates include at least two which are arranged at intervals on the bottom plate in the squirrel cage, each discharge plate is electrically connected to the control circuit board and adjacent discharge plates are connected to different voltage power supply terminals;

[0011] It is characterized by: it also includes

[0012] The first infrared sensor includes a first infrared transmitter and a first infrared receiver which are arranged on two sides of the mouse cage and are electrically connected to the control circuit board. The light beam emitted by the first infrared transmitter is located above one of the discharge plates, and the distance between the light beam and the rear edge of the discharge plate in the horizontal direction satisfies that when the light beam is triggered, the mouse steps on two adjacent discharge plates.

[0013] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: the first infrared sensor is arranged at the front of the squirrel cage, and the second infrared sensor is also arranged at the rear of the squirrel cage, and the second infrared sensor includes a second infrared transmitter and a second infrared receiver which are respectively arranged on both sides of the entrance and electrically connected to the control circuit board.

[0014] For the sake of structural aesthetics and convenient installation, the squirrel cage includes an upper shell and a lower shell that can be matched with each other, the upper shell includes a mounting base and a shell cover arranged on the mounting base, a mounting cavity is provided between the mounting base and the shell cover, and the control circuit board is arranged in the mounting cavity.

[0015] In order to facilitate the setting of the first infrared sensor and the second infrared sensor, and to facilitate the electrical connection of the first infrared sensor and the second infrared sensor, avoid the electrical connection wires being located outside, and ensure safety in use, mounting feet are respectively extended downward at the setting positions corresponding to the first infrared transmitter, the first infrared receiver, the second infrared transmitter and the second infrared receiver on the mounting substrate, and the first infrared transmitter, the first infrared receiver, the second infrared transmitter and the second infrared receiver are arranged at the lower ends of the mounting feet.

[0016] In order to avoid the accidental killing of reptiles such as cockroaches and the like, which would cause the mousetrap to no longer kill mice, the first infrared transmitter and the first infrared receiver are arranged on both sides of the mouse cage close to and higher than the discharge plate.

[0017] In order to induce mice to crawl toward the position of the first infrared sensor and increase the probability of catching and killing mice, a bait area for placing bait is placed at the front end of the mouse cage, and the first infrared sensor is arranged close to the bait area and behind the bait area.

[0018] In order to facilitate throwing bait and prevent mice from escaping from the placement opening, the front end face of the mouse cage has a placement opening for throwing bait, and the placement opening is covered with a baffle, the upper end of the baffle is rotatably connected to the inner wall of the mouse cage and can only be turned inward.

[0019] In order to facilitate the smell of the bait to be distributed and lure mice, the baffle is provided with openings.

[0020] Optionally, the inlet is arranged at the rear end face of the cage or the rear part of one side wall of the cage. When the inlet is arranged at the rear part of one side wall of the cage, the probability of mice escaping when the discharge plate is energized can be reduced.

[0021] The technical solution adopted by the present invention to solve the third technical problem is: a method for using a mousetrap, characterized in that it includes the following steps:

[0022] Detect and obtain resistance signals on two adjacent discharge plates to determine whether the resistance signals change;

[0023] When the resistance change signal is detected, the first infrared sensor and the second infrared sensor are started to work;

[0024] If the signal that the light beam of the first infrared sensor, the second infrared sensor or only the second infrared sensor is blocked is obtained at the same time, it is determined that no mouse has entered the mouse cage, and the discharge plate is not supplied with high voltage power;

[0025] If only the signal that the light beam of the first infrared sensor is blocked is obtained, it is determined that the mouse has entered the mouse cage, and the control circuit board supplies high voltage power to the discharge board.

[0026] Compared with the prior art, the advantage of the present invention is that the mousetrap in the present invention adjusts the setting position of the first infrared sensor so that the setting position of the first infrared sensor can better cooperate with the discharge plate to discharge and kill mice, thereby reducing the chance of mice escaping and increasing the probability of the mousetrap catching and killing mice.

[0027] In addition, the mousetrap of the present invention is provided with a second infrared sensor at the entrance, and the second infrared sensor can play a protective role, that is, when a pet or a person's arm enters the mouse cage, it can avoid triggering the discharge plate to discharge, thereby improving the safety of the mousetrap.

[0033] The present invention is further described in detail below with reference to the accompanying drawings.

[0034] like Figures 1 to 4 As shown, a mousetrap in this embodiment includes a mouse cage 1, a control circuit board, a discharge plate 2, a first infrared sensor 3, a second infrared sensor 4, and an indicator light 5.

[0035] like Figure 2 and Figure 3 As shown, the cage 1 is box-shaped as a whole, and the cage 1 has a housing cavity for placing mice therein. The cage 1 includes an upper shell 11 and a lower shell 12 that can be matched with each other, and the housing cavity mentioned above is formed between the upper shell 11 and the lower shell 12. The upper shell 11 includes a mounting substrate 111 and a shell cover 112 that covers the mounting substrate 111. There is a mounting cavity between the mounting substrate 111 and the shell cover 112, and the control circuit board is arranged in the mounting cavity. The control circuit board may include a controller and a peripheral circuit electrically connected to the controller. The control circuit board may be provided with a plug that can be electrically connected to an external power source, or a battery may be installed in the mounting cavity to power the control circuit board. In this embodiment, a battery holder for installing a battery is provided in the mounting cavity, and the battery holder is electrically connected to the control circuit board. After the battery is installed in the battery holder, it can be electrically connected to the control circuit board. In this embodiment, 4 batteries are used for power supply. At the same time, corresponding to the position where the battery is installed, the shell cover 112 is provided with a battery cover 1121 that can be detachably installed. In addition, an indicator light 5 is embedded in the shell cover 112, and the indicator light 5 is electrically connected to the control circuit board, so that the working state of the mousetrap is determined according to the control of the control circuit board. In addition, a power switch 6 electrically connected to the control circuit board can be embedded in the shell cover 112 to control the on and off of the battery. The rear portion of the mouse cage 1 has an entrance 10 for mice to enter. Figure 1 As shown, the inlet 10 can be arranged on the rear end surface of the cage 1, such as Figure 4As shown, the entrance 10 is arranged at the rear of one side wall of the cage 1. When the entrance 10 is arranged at the rear of one side wall of the cage 1, the probability of the mouse escaping after entering the cage 1 while the discharge plate 2 is energized can be reduced, thereby increasing the probability of catching and killing the mouse.

[0036] At least two discharge plates 2 can be selected according to the length of the squirrel cage 1, and these discharge plates 2 are arranged at intervals on the bottom plate in the squirrel cage 1, each discharge plate 2 is electrically connected to the control circuit board, and different voltage power supply terminals are connected to adjacent discharge plates 2. In this embodiment, two discharge plates 2 are provided, one of which is a rectangular metal plate, and the other discharge plate has two spaced-apart metal plate bodies, which are respectively located at the two ends of the rectangular metal plate and are spaced from the rectangular metal plate, and the two metal plate bodies are connected by a strip-shaped metal strip, which can be connected as an integral body or by a split body, and the metal strip is surrounded by the outside of the rectangular metal plate and isolated from the rectangular metal plate. This setting structure can facilitate the discharge plate to be energized, avoid connecting too many voltage power supply terminals, simplify the structure, and ensure the reliability of power supply.

[0037] The first infrared sensor 3 includes a first infrared transmitter and a first infrared receiver which are relatively arranged on both sides of the mouse cage 1 and electrically connected to the control circuit board. The light beam emitted by the first infrared transmitter is located above one of the discharge plates 2, and the distance between the light beam and the rear edge of the discharge plate 2 in the horizontal direction satisfies that when the light beam is triggered, the mouse steps on two adjacent discharge plates 2.

[0038] The first infrared sensor 3 is arranged at the front of the cage 1, and the second infrared sensor 4 is also arranged at the rear of the cage 1. The second infrared sensor 4 includes a second infrared transmitter and a second infrared receiver which are respectively arranged at both sides of the entrance 10 and electrically connected to the control circuit board.

[0039] like Figure 2 and Figure 3 As shown, in order to facilitate the installation of the first infrared sensor 3 and the second infrared sensor 4, and to facilitate the electrical connection of the first infrared sensor 3 and the second infrared sensor 4, to avoid the electrical connection line being located outside, and to ensure safety in use, mounting feet 113 are respectively extended downward from the installation positions corresponding to the first infrared transmitter, the first infrared receiver, the second infrared transmitter and the second infrared receiver on the installation substrate 111, and the first infrared transmitter, the first infrared receiver, the second infrared transmitter and the second infrared receiver are arranged on the inner side of the lower end of the mounting feet 113. The first infrared transmitter and the first infrared receiver are arranged oppositely in the horizontal line, and the second infrared transmitter and the second infrared receiver are arranged oppositely in the horizontal line. When there is no obstruction, the first infrared receiver can receive the light beam signal emitted by the first infrared transmitter, and the second infrared receiver can receive the light beam signal emitted by the second infrared transmitter.

[0040] In addition, in order to avoid the accidental killing of reptiles such as cockroaches, which would cause the mousetrap to no longer kill mice, the first infrared transmitter and the first infrared receiver are arranged on both sides of the mouse cage 1 close to and higher than the discharge plate 2. In this embodiment, the lower end of the mounting foot 113 is slightly higher than the upper surface of the discharge plate 2, so that the first infrared transmitter and the first infrared receiver are higher than the discharge plate 2, thereby avoiding the accidental triggering of the mousetrap caused by insects or other small insects.

[0041] In order to lure mice to crawl to the position of the first infrared sensor 3 and increase the probability of catching and killing mice, a bait area 101 for placing bait is placed at the front end of the mouse cage 1, and the first infrared sensor 3 is close to the bait area 101 and arranged behind the bait area 101, that is, the first infrared sensor 3 is arranged at the front of the mouse cage 1, and the second infrared sensor 4 is arranged at the rear of the mouse cage 1. There is a sufficiently long distance between the first infrared sensor 3 and the second infrared sensor 4. When a mouse triggers the first infrared sensor 3, the second infrared sensor 4 will not be triggered at the same time. In this way, by detecting the detection signals of the first infrared sensor 3 and the second infrared sensor 4, it can be effectively determined whether the person entering the mouse cage 1 is a mouse, thereby avoiding the accidental start of the discharge plate 2.

[0042] like Figure 2 and Figure 3 As shown, in order to facilitate throwing bait and prevent mice from escaping from the placement opening, the front face of the mouse cage 1 has a placement opening for throwing bait, and the placement opening is covered with a baffle 102, the upper end of the baffle 102 is rotatably connected to the inner wall of the mouse cage 1 and can only be turned inward. In order to facilitate the smell of the bait to be distributed and lure mice, the baffle 102 is provided with an opening 103.

[0043] The mousetrap of the present invention adjusts the setting position of the first infrared sensor 3 so that the setting position of the first infrared sensor 3 can better cooperate with the discharge plate 2 to discharge and kill mice, reducing the probability of mice escaping and increasing the probability of the mousetrap to kill mice. In addition, the mousetrap of the present invention adds a second infrared sensor 4 at the entrance 10, and the second infrared sensor 4 can play a protective role, that is, when a pet or a person's arm enters the mouse cage 1, it can avoid triggering the discharge plate 2 to discharge, thereby improving the safety of the mousetrap.

[0044] The method for using the mousetrap of the present invention comprises the following steps:

[0045] When the mouse cage 1 is in an initial state with no animal entering, the first infrared sensor 3 and the second infrared sensor 4 are both in a closed state;

[0046] Detect and obtain the resistance signals on the two adjacent discharge plates 2 to determine whether an animal has entered the cage 1; in this embodiment, the resistance signals of the two discharge plates 2 located at the rear of the cage 1 are detected to improve the detection speed. When a mouse or other animal or insect enters, the resistance between the two discharge plates 2 at the rear of the cage 1 will change. When the change signal is detected, the control circuit on the control circuit board is awakened from the low-power standby state to determine whether an animal has entered;

[0047] After the control circuit is awakened, the first infrared sensor 3 and the second infrared sensor 4 are started to work, that is, the first infrared transmitter and the second infrared transmitter both emit infrared beams. When the beams are not blocked, the first infrared receiver and the second infrared receiver receive the infrared beam signals of the first infrared transmitter and the second infrared transmitter respectively. When the corresponding beams are blocked, the infrared beam signals cannot be received.

[0048] If the control circuit board can simultaneously obtain the signal of the first infrared sensor 3, the second infrared sensor 4, or only obtain the signal that the light beam of the second infrared sensor 4 is blocked, it is judged that a non-mouse has entered the mouse cage 1, and the control circuit board controls not to supply high voltage to the discharge plate 2; usually, if the mouse cage 1 is entered by an animal larger than a mouse, such as a rabbit or a kitten, or a human arm enters the mouse cage 1, the light beam signals of the first infrared sensor 3 and the second infrared sensor 4 will be blocked, and the discharge plate 2 cannot be allowed to discharge at this time to avoid accidental injury; and if only the light beam of the second infrared sensor 4 is blocked, it may be a situation where a human finger or a small animal's head tentatively extends into the mouse cage 1, and false trigger protection is also required at this time, that is, the second infrared sensor 4 mainly plays a safety protection role, so when the light beam signal of the second infrared sensor 4 is blocked, the discharge plate 2 cannot be allowed to discharge, and false trigger protection is achieved;

[0049] Due to the special positional relationship between the first infrared sensor 3 and the discharge plate 2, if only the signal of the blocked light beam of the first infrared sensor 3 is obtained, and the second infrared sensor 4 is in a state where it can receive the light beam signal, it is judged that a mouse has entered the cage 1, and the mouse has entered the inner position of the cage, and the mouse's limbs are respectively stepped on two adjacent discharge plates 2, then the control circuit board supplies high voltage to the discharge plate 2, and then the discharge plate 2 discharges to kill the mouse entering the cage 1. The working voltage of the discharge plate 2 is 5000-10000V, and the killing of the mouse can be ensured by controlling the power-on time of the discharge plate 2. According to the different working voltages of the discharge plate 2, the power-on time of the discharge plate 2 can be controlled to be appropriately selected between 30 seconds and 120 seconds.

[0050] In addition, after the mouse is captured and killed, the control circuit board controls the discharge plate 2, the first infrared sensor 3, and the second infrared sensor 4 to stop working. At the same time, the control circuit board can control the indicator light 5 on the upper shell 11 to flash regularly, prompting the user that there is a captured mouse in the mouse cage 1, so that the user can deal with the captured mouse in time. After the user deals with the mouse in the mouse cage 1, the mousetrap is adjusted to be in the standby state again.

[0051] The method for using the mousetrap of the present invention determines whether an animal has entered the mouse cage 1 based on the resistance signal on the discharge plate 2, and activates the first infrared sensor 3 and the second infrared sensor 4 when it is determined that an animal has entered the mouse cage 1, thereby avoiding the first infrared sensor 3 and the second infrared sensor 4 being in the detection state all the time, reducing power consumption, and greatly prolonging the standby time of the mousetrap, especially for a battery-powered mousetrap.
