Description

Technical Field

[0001] This utility model relates to a termite extermination device, and more particularly to a termite extermination pesticide spraying device. Background Technology

[0002] Termites are a harmful organism that poses a serious threat to building safety and property. Their control faces two main challenges: first, the insidious nature of their damage makes it difficult to detect infestations in a timely manner using traditional methods; second, the lag in control actions means that by the time termite infestation is discovered, the termite colony has often already matured and caused substantial damage.

[0003] In existing termite control technologies, "monitoring" and "extermination" are usually two independent and separate processes. Common monitoring devices (such as wooden bait stations) can only perform periodic manual checks to determine the presence of termite activity. Once termite activity is confirmed through monitoring, professionals need to return to the site, remove the monitoring device, and replace it with a separate extermination device (such as a poison bait station), or implement separate extermination measures such as chemical injection. This separate "monitor first, then exterminate" model has significant drawbacks: First, there is a delay in response, with a time window between termite discovery and extermination action, during which the termite colony continues to expand and cause damage; second, it is inefficient, requiring multiple manual interventions, increasing labor and time costs; third, it may disturb the termites, as replacing the device may cause them to abandon the feeding site and instead harm other unmonitored areas, significantly reducing the effectiveness of extermination.

[0004] Therefore, there is an urgent need in this field for a solution that can organically integrate monitoring and extermination functions. An ideal technical solution should be able to automatically or remotely trigger the extermination mechanism upon detecting termite activity, without requiring device replacement or complex manual operations. This is particularly effective for precise and timely spraying to exterminate termite colonies that have reached a certain size and are exhibiting stable activity. This not only significantly shortens the response time from detection to control but also effectively utilizes termite aggregation behavior to improve pesticide delivery efficiency, thereby fundamentally enhancing the overall effectiveness and efficiency of termite control. Utility Model Content

[0005] The purpose of this invention is to provide a termite extermination spraying device to quickly and effectively exterminate termites after detecting large-scale termite activity.

[0006] A termite extermination spraying device, comprising

[0007] The shell is provided with an installation cavity, a gas cylinder storage cavity and a powder hopper in sequence. The powder hopper is connected to the gas cylinder storage cavity, and at least one spraying channel is provided on the wall of the powder hopper.

[0008] A piercing mechanism is disposed in the mounting cavity and has a piercing needle that can extend axially;

[0009] A gas storage cylinder is disposed in a gas cylinder storage cavity, and the piercing needle extends axially to pierce the gas storage cylinder;

[0010] Insecticide powder is placed in the powder hopper, and after the pressurized gas is released from the gas storage cylinder, it is pumped out of the powder hopper through the spray channel.

[0011] Preferably, the spraying channel is opened towards the side where the bait stick is located.

[0012] Preferably, the puncture mechanism includes a threaded sleeve disposed between the mounting cavity and the gas cylinder storage cavity, a screw rod is screwed into the threaded sleeve, the puncture needle is coaxially connected to the end face of the screw rod facing the gas cylinder, the screw rod is provided with an axially extending slide rail on the side facing away from the gas cylinder, the slide rail is prismatic in shape, a slider is slidably inserted in the slide rail, and a motor coaxially disposed with the threaded sleeve is also mounted in the mounting cavity, the output shaft of the motor is coaxially connected to the slider.

[0013] Preferably, the powder compartment is provided with a powder box, the insecticidal powder is placed in the powder box, the powder box has a powder outlet and an air inlet, the powder outlet mask is provided on the spraying channel, the powder box and the compartment wall of the powder compartment form an air inlet channel for compressed gas to enter the powder box, and the air inlet channel is connected to the air inlet.

[0014] Preferably, a one-way valve is embedded in the air inlet of the powder box.

[0015] Preferably, the air intake channel is provided with a support rib, which is supported at the bottom of the one-way valve.

[0016] Preferably, a diaphragm is pressed over the outlet of the spraying channel.

[0017] To achieve the above objectives, this utility model provides the following technical solution:

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model integrates the extermination system into the monitoring device. Once termite activity is confirmed through monitoring (such as through remote sensors or manual inspection), the piercing mechanism can be triggered immediately by an electrical signal to complete the spraying of pesticide powder within seconds, achieving zero delay from "discovery" to "extermination" and greatly improving the efficiency of prevention and control.

[0020] 2. Precise Targeting and Swarm Elimination: The spraying channel is opened towards the bait sticks, allowing the pesticide powder to precisely cover areas where termites are densely active. Termites contaminated with the powder spread the pesticide within the colony after returning to their nest through behaviors such as licking each other, thus eradicating the entire nest.

[0021] 3. Automation and remote control: The puncture mechanism is driven by a motor, which is easy to integrate with Internet of Things (IoT) technology to achieve remote wireless control and triggering, greatly reducing the number of manual on-site interventions and costs.

[0022] 4. Powered by a gas cylinder, the gas ejection is powerful and rapid. Compared to gas storage devices controlled by solenoid valves, this solution uses an independent, sealed gas cylinder, which has the characteristic of long-term gas preservation, making it particularly suitable for long-term termite monitoring.

[0023] 5. The modular powder box design facilitates the replacement and replenishment of powder. At the same time, the air intake channel design formed by the powder box and the powder compartment wall can effectively reduce the backflow of powder into the gas cylinder storage chamber when the medicine is blown out, ensuring that the powder is used to the maximum extent.

[0024] 6. A one-way valve is installed to further limit the backflow of powder into the gas cylinder storage chamber.

[0025] 7. A diaphragm is installed to keep the powder dry in the underground environment, ensuring smooth and uniform powder spraying. Attached Figure Description

[0032] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 The termite extermination spraying device shown is prismatic in shape, similar to the bait stick in a termite monitoring device. During assembly, it can directly replace the bait stick in the existing termite monitoring device, achieving rapid replacement.

[0037] In this embodiment, the termite extermination spraying device includes a housing 1, the interior of which, from top to bottom, consists of an installation cavity 101, a gas cylinder storage cavity 102, a powder storage chamber 103, and at least one spraying channel 106 located at the powder storage chamber 103.

[0038] Combination Figure 2The puncture mechanism 2 is installed inside the mounting cavity 101 and is used to puncture the gas cylinder 3 installed in the gas cylinder storage cavity 102. The puncture mechanism 2 includes a threaded sleeve 201 fixed to the partition wall between the mounting cavity 101 and the gas cylinder storage cavity 102. A screw 202 is screwed into the threaded sleeve 201, and a puncture needle 203 is coaxially fixed on the side of the screw 202 facing the gas cylinder 3. At the same time, a square-section slide rail 204 is machined on the side of the screw 202 facing away from the gas cylinder 3 (in some embodiments, the slide rail can also be a polygonal regular prism structure such as a triangular prism or a pentagonal prism). A slider 205 is embedded in the slide rail and can slide along the axial direction. A motor 206 is fixedly mounted inside the mounting cavity 101, and its output shaft is coaxially connected to the slider 205. When a trigger signal is received, the motor 206 starts and drives the slider 205 to rotate. Due to the cooperation between the slide rail 204 and the slider 205, the screw 202 rotates and, driven by the thread in the threaded sleeve 201, makes axial movement, thereby pushing the piercing needle 203 to pierce the gas cylinder 3 located in the gas cylinder storage chamber 102. After the gas cylinder 3 is pierced, the motor 206 reverses, taking the piercing needle 203 out of the gas cylinder 3, and the compressed air in the gas cylinder 3 can be ejected from the piercing port.

[0039] like Figure 1 and Figure 3 As shown, after the gas cylinder 3 is punctured, high-pressure carbon dioxide or nitrogen gas is released instantly. The insecticidal powder 5 (such as flufenoxuron, imidacloprid, and other powdered stomach poisons) filled in the powder compartment 103 is then sprayed out of the shell through the spray channel 106 towards the bait stick into the bait stick or ant bridge where termites are active, under the action of the pressurized gas.

[0040] In some embodiments, to facilitate efficient filling of the insecticidal powder 5, the insecticidal powder 5 is pre-filled in a powder box 4. During assembly or replacement, the powder box 4 is simply placed in the powder hopper 103. It should be noted that the powder box 4 is equipped with a discharge port 402 and an air inlet 401. The discharge port 402 covers the spraying channel 106, connecting it to the spraying channel 106, while the air inlet 401 communicates with the gas cylinder storage chamber 102, allowing the compressed gas to enter the powder box 4 through the air inlet 401 and then spray the insecticidal powder 5 stored in the powder box 4 through the discharge port 402 and the spraying channel 106.

[0041] In some embodiments, there is also a preferred structure, namely, by adjusting the position of the powder box 4 in the powder chamber 103, the chamber wall of the powder chamber 103 and the powder box 4 form a narrow air intake channel 104. This air intake channel guides compressed air into the powder box 4, and at the same time reduces the alternation of compressed gas between the gas cylinder storage chamber 102 and the powder chamber 103, so as to prevent some of the insecticide powder from entering the gas cylinder storage chamber 102 due to turbulence when the compressed air blows out the insecticide powder 5.

[0042] In some embodiments, the following improvement is also provided: a one-way valve 6 made of rubber is installed at the air inlet 401 of the powder box 4. External gas passes through the air inlet channel 104 (i.e., the gap between the powder box 4 and the chamber wall) to open the one-way valve 6 and enter the box, thereby achieving one-way flow of compressed gas and completely preventing the backflow of insecticidal powder 5. Preferably, a supporting rib 105 is also provided in the air inlet channel 104 to support the one-way valve 6 from below and prevent it from falling out of the powder box 4 due to the impact of high-pressure gas.

[0043] In this scheme, the high-pressure gas entering the powder box 4 agitates and mixes the powder 5, forming a gas-solid two-phase flow, which is then sprayed out at high speed from the outlet 402. In order to improve the utilization rate of the powder, the spraying channel 106 is directly facing the bait stick 100 (the area where termites are concentrated).

[0044] In addition, to ensure that the insecticide powder remains dry for a long time, a diaphragm 7 is attached to the outlet of the spraying channel 106 to prevent moisture from the soil from entering. When compressed gas enters the space containing the insecticide powder 5, the diaphragm 7 is broken by the airflow, and the insecticide powder is finally sprayed onto the bait stick 100 and the surrounding soil.

[0045] The working process of this utility model is as follows: When the termite monitoring device detects a large number of termites moving on the termite bridge 100, the control center sends a command to the motor 206. The motor 206 operates, driving the stinger 203 to move down and pierce the gas storage cylinder 3. Afterward, the motor 206 reverses and exits the gas storage cylinder 3. The high-pressure gas in the gas storage cylinder 3 rushes into the powder box 4 within 0.1-0.5 seconds, instantly pumping the insecticidal powder 5 onto the targeted bait stick 100, completing one extermination action. Afterward, a new gas storage cylinder 3 and powder box 4 can be replaced to reset the device and prepare for the next cycle.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
