Description

Technical Field

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

[0002] Termites are harmful to human life, production and even survival. The threat posed by termites and other insect pests and rodent pests is particularly serious in tropical and subtropical regions around the world. The main hazards are: spreading diseases, destroying the ecological environment, harming buildings and building materials, harming agricultural and forestry crops, stealing food, destroying textiles, entering human settlements and causing residents to feel uneasy, etc.

[0003] For example, termites can eat all plants, and the formic acid secreted by their bodies can also corrode steel bars and denature concrete. Termites have caused a lot of damage to people's daily lives, including damage to buildings, dams, crops, books, underground cables, etc. The damage is hidden. For example, the damage caused by termites to buildings, especially to brick-wood and wooden structures, is often hidden inside the structure. The surface of the damaged object looks intact, but in fact it is riddled with holes, which often causes the collapse of the house, resulting in property losses and casualties.

[0004] For a long time, the method of preventing and controlling termites is drug prevention, which is to apply insecticides on the ground or in the soil. The insecticides used will cause environmental pollution and threaten human health. Therefore, people have proposed drug-free prevention and designed a termite control device. A bait strip that termites like to eat is placed in a shell with an opening as bait. After a period of time, the device is taken out to see if the bait strip has been eroded to determine whether there are termites. Since this device is set up every few meters in the building, the workload is very large. Summary of the invention

[0005] In view of the above technical problems, the present invention 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 turning the series circuit on and off.

[0006] To achieve the above object, the technical solution of the present invention is: a termite detection device, comprising a housing with openings for allowing termites to enter, a support, a circuit board and a plurality of bait strips that termites like to eat, the circuit board being arranged on the bait strip, the bait strip having a conductive coating inside, 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 bait strips are arranged in the housing, the pillars and 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 the bait strip 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 via a metal sheet.

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

[0013] Preferably, the conductive coating and the passage 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, it also includes a top cover, 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 also 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 arranged in the housing, and the support and the bait strip are arranged in parallel. A plurality of elastic parts are arranged between the support and the bait strip or between the bait strips. A conductive coating is provided inside the bait strip, and the conductive coatings in all the bait strips are connected in series, and are connected in series with the circuit board to form a series circuit. Under normal circumstances, the series circuit is a conductive path, and the two ends of the elastic part are respectively against the bait strip and the support or between the bait strip. In the case of termites, the termites bite the bait strip, causing the density of the bait strip to change. Due to the action of the elastic part, the bait strip breaks, and then the conductive coating attached to the bait strip is also destroyed and disconnected, which causes the series circuit to change from a path to an open circuit. Since a detection chip for detecting the continuity of the series circuit is provided on the circuit board, after the series circuit is disconnected, the detection chip will send a signal to the cloud to determine that there are termites here. The termite detection device of the present invention is a drug-free prevention method, does not cause pollution to the environment, and has a very high accuracy rate; and the conductive coating is coated on the inside of the bait strip instead of being attached to the outside of the bait strip, thereby preventing false alarms.

[0024] In view of the current problem of termite control, the present invention 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 of a passage, and elastic parts are 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 the elastic force of the elastic parts causes the bait strips to break, and then the conductive coating on the bait strips is also disconnected along with the bait strips, so as to judge whether there are termites 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 also 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 a circuit board 4. The outer shell is fixedly connected to the top cover 1, and the outer shell and the top cover 1 form an inner cavity. The bait strips 2, the circuit board 4, and the pillars 6 are all in the inner cavity. The circuit board 4 is arranged on the top of the bait strip 2, and the top cover 1 can be used to protect the circuit board 4. The bait strips 2 and the pillars 6 are arranged vertically. In a specific embodiment, for example, in this embodiment, a base 7 is arranged at the bottom of the outer shell, and the base 7 is fixedly connected to the bottom of the pillar 6. The pillar 6 can be used to support the circuit board 4, and the bait strip 2 is also fixed on the base 7.

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

[0028] A plurality of elastic members 8 are arranged between the bait strip 2 and the support 6, and the two ends of the elastic members 8 are respectively against the bait strip 2 and the support 6; or Figure 1-2 As shown, a plurality of elastic members 8 are arranged between the bait strips 2, and the two ends of the elastic members 8 respectively abut against two opposite bait strips 2 or two adjacent bait strips 2. Specifically, during implementation, through holes through which the elastic members 8 pass can be arranged 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 of disconnection of the series circuit to the cloud, thereby judging that termites are present.

[0031] A conductive coating 3 with a nanometer thickness is provided inside the bait strip 2. The conductive coating 3 can be a water-insoluble conductive coating sprayed on the inside of the bait strip 2 by spraying paint, or brushed on the inside of the bait strip 2 by brushing paint, or electroplated or deposited in a thin film, and no limitation is made here. The conductive coating 3 in 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 passage. In the presence of termites, the termites bite 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 is broken, and then the conductive coating 3 is also damaged and disconnected. Once the conductive coating 3 in the bait strip 2 is damaged by termites, the series circuit changes from a conducting state to a disconnected state. Since a detection chip for detecting the continuity of the series circuit is provided on the circuit board 4, after the series circuit is disconnected, the detection chip will send a signal to determine the presence of termites. Since the support 6 is provided with an elastic member 8, the series circuit is not completely disconnected until 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 pollute the environment.

[0032] Moreover, the conductive coating 3 is placed inside the bait strip 2 in this embodiment, which reduces the false alarm rate compared to the wire fixed on the outer peripheral side of the bait strip 2. Since other small animals and small creatures besides termites can easily break the wire attached to the outer side of the bait strip and cause a false alarm, or other external reasons cause the graphite paper to break, such as rain erosion, etc., the conductive coating 3 is placed inside the bait strip 2 in this embodiment to avoid the above false alarms. Only when termites gnaw on the bait strip, causing the density of the bait strip 2 to change, the elastic member 8 is disconnected, causing the conductive coating 3 to disconnect, will the conductive circuit be disconnected, so that the detection chip sends a signal.

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

[0034] Further, 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 follows 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. In this way, they often only eat the conductive coating lines thinner but not break them. As a result, even if termites appear, the device will not alarm.

[0036] like Figure 3 The conductive coating 3 shown is coated in the form of a zigzag line on the side of the first bait strip 201 and / or the second bait strip 202. Even if the annual ring shape is irregular or the processed strip wood is tilted, it does not affect the termites from chewing the wood along the grain and cutting the power circuit set by the conductive coating. Therefore, the conductive coating circuit in the zigzag line shape is more sensitive and the accuracy of the termite alarm is higher.

[0037] Further preferably, after termites bite the bait strip 2, it is ensured that the bait strip 2 can be broken and broken under the action of the elastic member 8. The thickness of the bait strip 2 is 5-15mm and the width is 15-25mm. Within this range, the complete bait strip 2 can resist the elastic force of the elastic member, and after being bitten by termites, it is easy to break under the elastic force of the elastic member 8, thereby improving the timeliness and responsiveness of judging termites. The elastic member 8 is preferably a spring.

[0038] The conductive coating 3 in the bait strip 2 can be connected in series through a wire. In order to prevent the wire from being affected by the soil and causing a false alarm, the wire exposed outside the bait strip 2 and the circuit board has a protective cover, which protects the wire from being damaged by a harsh soil environment such as moisture and acidity and causing a false alarm. The material of the protective cover can be the same as or different from the material of the bait strip 2. In this embodiment, the material of the protective cover is the same as the material of the bait strip 2. In this arrangement, once termites bite the protective cover, they may also bite off the wire, causing the series circuit to be disconnected, and it can also be determined that there are termites here.

[0039] See also 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 realize the series connection between the circuit board 4 and the conductive coating 3 (such as Figure 2 As shown), 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 in conjunction with 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 still fall within the protection scope of the present invention.
