Description

Technical Field

[0001] The utility model relates to the field of termite prevention and control, in particular to a termite detection device. Background Art

[0002] Termites pose a threat to human life, production, and even survival. Globally, the threat posed by termites, particularly insect pests and rodents, is particularly severe in tropical and subtropical regions. These hazards primarily include spreading disease, damaging the ecological environment, harming buildings and building materials, stealing crops and textiles, and entering human settlements, causing unrest.

[0003] For example, termites, a type of white ant, can eat all plants. Their formic acid, which corrodes steel and denatures concrete, can also cause significant damage to people's daily lives, including damage to buildings, dams, crops, books, and underground cables. This damage is often hidden. For example, termite damage to buildings, particularly those made of brick and wood, often occurs within the structure. While the surface of the affected object may appear intact, it is actually riddled with holes. This often causes building collapses, resulting in property damage and casualties.

[0004] For a long time, termite control relied on preventive medication, applying insecticides to the ground or soil. These pesticides can pollute the environment and pose a threat to human health. Therefore, a drug-free approach has emerged, with the design of a termite control device. This device contains a perforated housing containing bait strips favored by termites. After a period of time, the device is removed to inspect the strips for signs of erosion, thereby determining the presence of termites. However, since these devices are installed every few meters across a building, the workload is substantial. Utility Model Content

[0005] In response to the above technical problems, the utility model provides a termite detection device, which is a drug-free control device and will not pollute the environment. A series circuit is formed by a conductive coating and a circuit board, and the presence of termites is detected by switching the series circuit on and off.

[0006] To achieve the above objectives, the technical solution of the present utility model is as follows: a termite detection device, comprising a housing with openings allowing termites to enter, a support, a circuit board, and a plurality of bait strips favored by termites, the circuit board being disposed on the bait strips, the bait strips having a conductive coating therein, the conductive coating forming a series circuit with the circuit board, the circuit board being provided with a detection chip for detecting the continuity of the series circuit;

[0007] The pillars and the bait strips are arranged in the housing, the pillars and the bait strips are arranged vertically, and a plurality of elastic members are arranged between the pillars and the bait strips or between the bait strips;

[0008] Under normal conditions, the conductive coating and the circuit board form a conductive series circuit, and both ends of the elastic member respectively abut against the pillar and the bait strip, or both ends of the elastic member respectively abut against the adjacent or opposite bait strips.

[0009] Preferably, the bait strip is a cuboid, and comprises at least a first bait strip and a second bait strip, and the mutually contacting sides of the first bait strip and / or the second bait strip are coated with a conductive coating.

[0010] Preferably, the conductive coating on the mutually contacting sides of the first bait strip and / or the second bait strip is in the shape of a broken line.

[0011] Preferably, the conductive coating and the path formed by the circuit are connected in series through a metal sheet.

[0012] Preferably, the thickness of the bait strip is 5-15 mm.

[0013] Preferably, the conductive coating and the path formed by the circuit board are connected in series via a wire, and the wire exposed outside the bait strip has a protective sheath.

[0014] Preferably, the material of the protective cover is the same as that of the bait strip.

[0015] Preferably, a top cover is further included, the bait strip is arranged in the outer shell, and the outer shell and the top cover are fixedly connected.

[0016] Preferably, an alarm device is further provided in the top cover, and the alarm device is electrically connected to the circuit board.

[0017] Preferably, the elastic member is a spring.

[0018] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0019] The termite detection device provided by the present invention includes a housing, a support, a bait strip, and a circuit board. The support and the bait strip are both disposed within the housing, and the support and the bait strip are disposed parallel to each other. A plurality of elastic members are disposed between the support and the bait strip, or between the bait strips. The bait strips are provided with a conductive coating, and the conductive coatings within all the bait strips are connected in series, and in series with the circuit board to form a series circuit. Under normal circumstances, the series circuit is a conductive path, with the ends of the elastic members respectively resting against the bait strips and the support or between the bait strips. In the presence of termites, the termites gnaw on the bait strips, causing the density of the bait strips to change. Due to the action of the elastic members, the bait strips break, and the conductive coating attached to the bait strips is also damaged and disconnected, causing the series circuit to change from a connected circuit to a disconnected circuit. Since the circuit board is provided with a detection chip for detecting the continuity of the series circuit, after the series circuit is disconnected, the detection chip will send a signal to the cloud, thereby determining the presence of termites. The termite detection device of the present invention is drug-free, does not pollute the environment, and has a very high accuracy rate. Furthermore, the conductive coating is applied to the inside of the bait strip rather than attached to the outside of the bait strip, thereby preventing false alarms.

[0024] In response to the current problem of termite control, the utility model provides a termite detection device, in which a conductive coating is arranged in a bait strip, and the conductive coating and the circuit board form a series circuit with a path. At the same time, an elastic member is arranged between the bait strip and the support or between the bait strips. As termites bite the bait strips, the density of the bait strips increases, and under the action of the elastic force of the elastic member, the bait strips are broken, and then the conductive coating on the bait strips is also disconnected along with the bait strips, so that the presence of termites can be judged by utilizing the on-off of the circuit.

[0025] The following is a further detailed description of a termite detection device proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description.

[0026] See Figure 1-3 A termite detection device includes an outer shell that allows termites to enter, a top cover 1, and a plurality of bait strips 2 that termites like to eat, pillars 6, and circuit boards 4. The outer shell is fixedly connected to the top cover 1. The outer shell and the top cover 1 form an inner cavity. The bait strips 2, circuit boards 4 and pillars 6 are all in the inner cavity. The circuit board 4 is arranged on the top of the bait strips 2. The top cover 1 can be used to protect the circuit board 4. The bait strips 2 and pillars 6 are arranged vertically. In a specific embodiment, for example, in this embodiment, a base 7 is provided at the bottom of the outer shell. The base 7 is fixedly connected to the bottom of the pillars 6. The pillars 6 can be used to support the circuit board 4. The bait strips 2 are also fixed on the base 7.

[0027] The bait strips 2 have a conductive coating 3 inside. The conductive coatings 3 in all the bait strips 2 are connected in series and electrically connected to a circuit board 4 to form a series circuit. A battery and a detection chip for detecting the continuity of the series circuit are set on the circuit board 4. When the detection chip detects that the series circuit is disconnected, it sends a signal to the cloud.

[0028] A plurality of elastic members 8 are provided between the bait strip 2 and the support 6, with both ends of the elastic members 8 respectively resting against the bait strip 2 and the support 6; or Figure 1-2 As shown, multiple elastic members 8 are arranged between the bait strips 2, and the two ends of the elastic members 8 respectively rest on two opposite bait strips 2 or two adjacent bait strips 2. Specifically, during implementation, through holes for the elastic members 8 to pass through can be provided on the pillars 6 to facilitate the connection between the elastic members 8 and the bait strips 2.

[0029] In a normal state, the conductive coating 3 and the circuit board 4 form a conductive series circuit, and the elastic member 8 is in a compressed state;

[0030] In the case of termites, the conductive circuit formed by the conductive coating 3 and the circuit board 4 is disconnected, and the detection chip sends a signal to the cloud indicating that the series circuit is disconnected, thereby determining that termites are present.

[0031] A nanometer-thick conductive coating 3 is provided within the bait strip 2. The conductive coating 3 can be a water-insoluble conductive coating sprayed onto the inside of the bait strip 2, applied by brushing, electroplating, or thin-film deposition, all of which are not limited here. The conductive coating 3 within each bait strip 2 is connected in series with the circuit board 4 to form a series circuit. Under normal circumstances, the series circuit is a pathway. In the presence of termites, the termites gnaw on the bait strip 2, causing the density of the bait strip 2 to change. Due to the action of the elastic member 8, the bait strip 2 breaks, and the conductive coating 3 is also damaged, causing it to disconnect. Once the conductive coating 3 within the bait strip 2 is damaged by termites, the series circuit changes from an on state to an off state. Since the circuit board 4 is provided with a detection chip for detecting the on and off of the series circuit, the detection chip will send a signal after the series circuit is disconnected, thereby determining the presence of termites. Since the support 6 is provided with an elastic member 8, the series circuit is completely disconnected only when the bait strip 2 is almost eaten by termites, thereby improving the responsiveness and accuracy of termite detection. In addition, the termite detection device is a drug-free prevention device and will not cause pollution to the environment.

[0032] Furthermore, this embodiment places the conductive coating 3 inside the bait strip 2, reducing the false alarm rate compared to wires attached to the outer periphery of the bait strip 2. Since small animals and organisms other than termites can easily break wires attached to the outside of the bait strip, causing false alarms, or other external factors can cause the graphite paper to break, such as rain, this embodiment places the conductive coating 3 inside the bait strip 2 to avoid these false alarms. Only when termites gnaw on the bait strip, causing the density of the bait strip 2 to change, the elastic member 8 breaks, and the conductive coating 3 breaks, will the conductive circuit be disconnected, causing the detection chip to transmit a signal.

[0033] Further preferably, an alarm device is provided in the top cover 1 , and the alarm device is electrically connected to the circuit board 4 . When the series circuit is in a disconnected state, the alarm device sends an alarm signal.

[0034] Furthermore, the bait strip 2 is rectangular, and the bait strip 2 includes at least a first bait strip 201 and a second bait strip 202. The first bait strip 201 and the second bait strip 202 are combined into a rectangular bait strip 2. The surfaces of the first bait strip 201 and / or the second bait strip 202 that contact each other have a conductive coating 3. The conductive coating 3 can completely cover the side surfaces of the first bait strip 201 and / or the second bait strip 202, or partially cover the side surfaces of the first bait strip 201 and / or the second bait strip 202. The shape is a straight line or a broken line, preferably as shown in FIG. Figure 3 The conductive coating is shown in the shape of a broken line.

[0035] Some termites have special habits when chewing bait strips. For example, termites suck wood according to the pattern of annual rings. This often only makes the conductive coating circuit thinner but does not break it. Therefore, even if termites appear, the device will not alarm.

[0036] like Figure 3 The conductive coating 3 is applied in a zigzag pattern on the sides of the first bait strip 201 and / or the second bait strip 202. Even if the growth rings are irregular or the processed wood strips are tilted, termites can still gnaw along the grain of the wood and break the conductive coating's electrical circuit. Therefore, the zigzag conductive coating circuit is more sensitive, and the termite alarm is more accurate.

[0037] Further preferably, after termites have gnawed on the bait strip 2, the elastic member 8 is capable of breaking the bait strip 2. The thickness of the bait strip 2 is 5-15 mm, and the width is 15-25 mm. Within this range, intact bait strips 2 can withstand the elastic force of the elastic member, yet easily break under the elastic force of the elastic member 8 after being gnawed by termites, thereby improving the timeliness and responsiveness of termite detection. The elastic member 8 is preferably a spring.

[0038] The conductive coating 3 within the bait strip 2 can be connected in series via wires. To prevent false positives caused by soil effects, the wires exposed outside the bait strip 2 and circuit board are protected with protective sheaths. These sheaths protect the wires from moisture, acidity, and other harsh soil environments, which could lead to false positives. The material of the protective sheaths can be the same as or different from that of the bait strip 2. In this embodiment, the material of the protective sheaths is the same as that of the bait strip 2. This arrangement ensures that if termites gnaw on the protective sheaths, they may also gnaw through the wires, breaking the series circuit and still detecting the presence of termites.

[0039] See Figure 2 In another embodiment, the conductive coating 3 in the bait strip 2 can be connected in series through the metal sheet 6. The metal sheet 6 can be used to connect one end of the metal sheet 6 to the circuit board 4, and the other end of the metal sheet 6 can be directly inserted between the first bait strip 201 and the second bait strip 202 to achieve the series connection of the circuit board 4 and the conductive coating 3 (such as Figure 2 As shown in the figure, the overall structure of the metal sheet is compact, no extra wires are required, and misjudgment caused by disconnection between the conductive coating and the circuit board is prevented.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they will still fall within the scope of protection of the present invention.
