Description

Technical Field

[0001] This utility model relates to the field of termite extermination technology, specifically a termite extermination powder spraying device. Background Technology

[0002] Termites are social insects that typically live in colonies and are highly destructive to wood and other cellulose-containing materials. There are various methods for termite control, including physical, chemical, and biological methods. The most common method is pesticide spraying, which involves spraying specialized insecticides into the termite activity area or around the nest, causing the termites to die upon contact with the pesticide. Commonly used insecticides include fipronil and deltamethrin.

[0003] For example, patent publication number CN219920082U provides a termite extermination powder spraying device, including a body, a storage bottle, and a fan. The fan is installed inside the body, and a powder spraying port is located at the front end of the body. The powder spraying port is connected to the fan's outlet via a connecting pipe. A downward-extending powder suction pipe is connected to the middle of the connecting pipe, and the storage bottle and the powder suction pipe are detachably connected. The advantages of this invention are: when going out, only multiple storage bottles containing different pesticides need to be carried. When targeting a specific type of termite, only the corresponding storage bottle needs to be installed at the powder suction pipe, thus avoiding the drawbacks of frequently filling or emptying the powder spraying device with residual pesticides, and avoiding the disadvantages of installing multiple powder spraying boxes, requiring multiple solenoid valves, resulting in high costs and easy clogging of the solenoid valves.

[0004] In the above scheme, the extermination powder is sprayed from one end of the hose during the powder spraying process. The flexible nature of the hose itself may cause irregular swaying during the powder spraying process, resulting in the powder being more dispersed after being sprayed, thereby reducing the extermination effect of the device on termites.

[0005] Therefore, a termite extermination powder spraying device is proposed to address the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies and solve the problem that the termite-killing powder is sprayed from one end of a hose during the spraying process, and the hose's inherent flexibility may cause irregular swaying during spraying, resulting in more dispersed powder and thus reducing the device's effectiveness in killing termites, a termite-killing powder spraying device is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The termite extermination powder spraying device of this utility model includes a spray gun body, a first spray pipe is clamped at the nozzle end of the spray gun body, a transition ring is fixedly connected to the inner wall of the first spray pipe near one end edge, a nozzle assembly is provided at one end of the first spray pipe, the nozzle assembly includes a second spray pipe, a connecting hose is connected to one end of the second spray pipe, one end of the connecting hose extends into the interior of the first spray pipe and splices with the transition ring, mounting grooves are symmetrically opened on the outer walls of both ends of the second spray pipe, an annular buckle is fixedly connected to the center of the side wall of the mounting groove, a rotating circular plate is clamped inside each of the two annular buckles, a connecting rod is fixedly connected to the side wall of the rotating circular plate, a threaded sleeve is fixedly connected between one end of the two connecting rods, and the threaded sleeve is screwed to the external thread of one end of the first spray pipe.

[0008] Preferably, the outer wall of the rotating circular plate is provided with a plurality of limiting teeth, which are equally spaced along the semicircular outer wall of the rotating circular plate.

[0009] Preferably, a limiting component is installed on the side wall of the mounting groove. The limiting component includes a spring, one end of which is fixedly connected to a positioning side plate, which is fixedly connected to the outer wall of the second nozzle.

[0010] Preferably, the other end of the spring is fixedly connected to an L-shaped slider, and one end of the L-shaped slider slides in contact with the side wall of the mounting groove.

[0011] Preferably, the other end of the L-shaped slider is fixedly connected to a limiting tooth, which can mesh with one of the limiting teeth.

[0012] Preferably, the other end of the L-shaped slider is fixedly connected to a limiting tooth, which can mesh with one of the limiting teeth.

[0013] Preferably, the sidewalls of the mounting groove are symmetrically fixed with limiting rails, and the inner wall of the limiting rails can engage with the outer walls of both ends of the mounting protrusion.

[0014] Preferably, a push-pull ring is fixed between the outer walls of the two limiting sliders.

[0015] The beneficial effects of this utility model are:

[0016] In this invention, a smooth transition between the first and second spray pipes is achieved through the interlocking of the transition ring and the connecting hose.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 - Figure 5This utility model provides a termite extermination powder spraying device, including a spray gun body 1. A first spray pipe 2 is fitted onto the nozzle end of the spray gun body 1. A transition ring 21 is fixedly connected to the inner wall of the first spray pipe 2 near one edge. A nozzle assembly 3 is provided at one end of the first spray pipe 2. The nozzle assembly 3 includes a second spray pipe 31. A connecting hose 32 is connected to one end of the second spray pipe 31. One end of the connecting hose 32 extends into the interior of the first spray pipe 2 and connects with the transition ring 21. Installation grooves 33 are symmetrically formed on the outer walls of both ends of the second spray pipe 31. Annular buckles 331 are fixedly connected to the center of the side walls of the installation grooves 33. Rotating circular plates 34 are fitted inside each of the two annular buckles 331. Connecting rods 341 are fixedly connected to the side walls of the rotating circular plates 34. A threaded sleeve 342 is fixedly connected between one end of the two connecting rods 341. The threaded sleeve 342 is connected to the first spray pipe 2. One end is externally threaded. After the spray gun body 1 is loaded with termite-killing powder through the powder cylinder, the power is turned on. Under air pressure, the powder is sprayed out through the first spray pipe 2 and then through the second spray pipe 31. The first spray pipe 2 and the second spray pipe 31 of the nozzle assembly 3 are connected by a transition ring 21 and a connecting hose 32. This connection is a rigid hinge, which prevents the powder outlet from swaying irregularly during the powder spraying process. The threaded sleeve 342 screwed to one end of the first spray pipe 2 is engaged with the annular buckle 331 in the mounting groove 33 by the rotating circular plate 34 at one end of the connecting rod 341. This allows the relative angle between the first spray pipe 2 and the second spray pipe 31 to change within a certain range. During this process, the connecting hose 32 is always engaged with the inner ring of the transition ring 21, ensuring the smooth operation of the powder spraying.

[0028] like Figure 4 As shown, the outer wall of the rotating circular plate 34 is provided with a plurality of limiting teeth 343. The plurality of limiting teeth 343 are equally spaced along the semicircular outer wall of the rotating circular plate 34. The limiting teeth 343 are auxiliary structures provided on the outer wall of the rotating circular plate 34 to limit the relative angle between the first nozzle 2 and the second nozzle 31.

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, a limiting component 4 is installed on the side wall of the mounting groove 33. The limiting component 4 includes a spring 41. One end of the spring 41 is fixedly connected to a positioning side plate 42, which is fixedly connected to the outer wall of the second nozzle 31. The other end of the spring 41 is fixedly connected to an L-shaped slider 43. One side wall of the L-shaped slider 43 contacts and slides against the side wall of the mounting groove 33. The other side wall of the L-shaped slider 43 is fixedly connected to a limiting tooth 431, which can mesh with one of the limiting teeth 343. The limiting component 4 is used to control the first nozzle. The structure limits the angle between the first nozzle 2 and the second nozzle 31. When the limiting tooth 431 at one end of the L-shaped slider 43 meshes with the limiting tooth 343, the relative angle between the first nozzle 2 and the second nozzle 31 is limited. The spring 41 installed between the positioning side plate 42 and the L-shaped slider 43 provides an elastic force for the L-shaped slider 43 to move away from the positioning side plate 42. In addition, the positioning side plate 42 and the L-shaped slider 43 as a whole have an elastic force to move closer to the rotating circular plate 34 and engage with the limiting tooth 343.

[0030] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, one end of the L-shaped slider 43 is fixedly connected to a mounting protrusion 432, and the side wall of the mounting groove 33 is symmetrically fixedly connected to a limiting rail 332. The inner wall of the limiting rail 332 can engage with the outer walls of both ends of the mounting protrusion 432. A push-pull ring 44 is fixedly connected between the outer walls of the two limiting sliders. The L-shaped slider 43 limits the overall movement of the L-shaped slider 43 by the engagement between the mounting protrusion 432 and the limiting rail 332. The L-shaped slider 43 can only reciprocate under the limitation of the limiting rail 332, which increases the rationality of the loading structure. When it is necessary to change the relative angle between the first nozzle 2 and the second nozzle 31, the push-pull ring 44 needs to be pulled outwards, and the L-shaped sliders 43 on both sides need to be moved away from the rotating circular plate 34 so that the limiting protrusion 431 disengages from the limiting tooth 343 before the position of the limiting component 4 can be changed.

[0031] Working principle: After the spray gun body 1 is loaded with termite-killing powder through the powder tank, the power is turned on. Under air pressure, the powder is sprayed out through the first spray pipe 2 and then through the second spray pipe 31. The first spray pipe 2 and the second spray pipe 31 of the nozzle assembly 3 are connected by a transition ring 21 and a connecting hose 32. This connection is a rigid hinge, which prevents the powder outlet from swinging irregularly during the spraying process. The threaded sleeve 342 screwed to one end of the first spray pipe 2 is engaged with the annular buckle 331 in the mounting groove 33 by the rotating circular plate 34 at one end of the connecting rod 341. This allows the relative angle between the first spray pipe 2 and the second spray pipe 31 to change within a certain range. During this process, the connecting hose 32 remains engaged with the inner ring of the transition ring 21. The limiting component 4 is a structure that limits the relative angle between the first spray pipe 2 and the second spray pipe 31. When the limiting tooth 431 at one end of the L-shaped slider 43 engages with the limiting tooth... When the teeth 343 mesh with each other, the relative angle between the first nozzle 2 and the second nozzle 31 is limited. The spring 41 installed between the positioning side plate 42 and the L-shaped slider 43 provides an elastic force for the L-shaped slider 43 to move away from the positioning side plate 42. The positioning side plate 42 and the L-shaped slider 43 as a whole have an elastic force to move closer to the rotating circular plate 34 and engage with the limiting teeth 343. The L-shaped slider 43 limits the position of the L-shaped slider 43 by the mutual engagement between the locking protrusion 432 and the limiting rail 332. The L-shaped slider 43 can only reciprocate under the limitation of the limiting rail 332, which increases the rationality of the loading structure. When it is necessary to change the relative angle between the first nozzle 2 and the second nozzle 31, the external push-pull ring 44 needs to be pulled to move the L-shaped slider 43 on both sides away from the rotating circular plate 34 and disengage the limiting protrusion 431 from the limiting teeth 343 before the position of the limiting component 4 can be changed.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
