[0001] This utility model relates to the field of insect control technology, and in particular to an insecticidal gun. Background Technology

[0002] In the field of pest control technology, traditional methods such as chemical spraying and electric shock devices have significant shortcomings. Chemical spraying relies on toxic substances, posing a long-term threat to the environment and health, while electric shock devices pose safety hazards, especially in home environments. Large air gun-type insecticides, although powerful, are expensive and complex to operate. Existing technologies fail to provide a safe and efficient pest control solution, particularly lacking in the ability to accurately kill small pests and in terms of ease of operation. Utility Model Content

[0003] The main purpose of this invention is to propose an insecticidal gun that aims to solve the problem that traditional insecticidal guns may cause harm to the environment and human health during use.

[0004] To achieve the above objectives, the insect-killing gun proposed in this utility model includes:

[0005] The gun body has a sleeve inside, and the sleeve has a barrel passage;

[0006] An elastic cartridge case is fitted onto one end of the sleeve. The inner cavity of the elastic cartridge case is connected to the barrel passage. The cross-sectional area of ​​the barrel passage gradually decreases from the end near the elastic cartridge case to the end away from the elastic cartridge case.

[0007] In one embodiment, the insecticidal gun further includes a connecting ring that connects the sleeve and the elastic cartridge. A limiting boss is formed at the end of the connecting ring away from the sleeve. The elastic cartridge is sleeved on the limiting boss, and a portion of the elastic cartridge is clamped between the limiting boss and the sleeve.

[0008] In one embodiment, the end of the connecting ring away from the elastic bladder is provided with an external thread, and the end of the sleeve near the elastic bladder is provided with an internal thread. The connecting ring is screwed to the sleeve through the cooperation of the external thread and the internal thread.

[0009] In one embodiment, the insecticidal gun further includes an annular component. A first limiting portion is formed on the outer wall of the sleeve near one end of the elastic cartridge. The annular component is sleeved on the first limiting portion and cooperates with the first limiting portion to clamp and fix the elastic cartridge.

[0010] In one embodiment, the annular member is a rubber ring.

[0011] In one embodiment, the insecticide gun further includes a magazine with a transparent viewing section.

[0012] In one embodiment, the gun body further includes a chamber cover and a grip, the chamber cover and the grip forming a first cavity; the magazine portion is disposed in the first cavity, the magazine forming a second cavity and a second through hole, the second through hole extending into the first cavity, the sleeve forming a first through hole, and the barrel passage communicating with the first through hole; in the initial state of the insecticide gun, the second through hole is isolated from the first through hole; in the loaded state of the insecticide gun, the second through hole, the first through hole and the barrel passage are sequentially connected.

[0013] In one embodiment, the magazine has a magazine-splitting groove at one end near the second through hole, the sleeve has a stepped partition plate, the magazine-splitting groove is vertically connected to the second through hole, the magazine-splitting groove is horizontally provided with a third through hole, and the stepped partition plate can be inserted into the third through hole; the magazine-splitting groove connects the second cavity and the second through hole.

[0014] In one embodiment, the chamber cover has a second limiting portion, the grip has a first fixing portion, the first fixing portion has a third limiting portion, the sleeve is connected to the first fixing portion, and the second limiting portion cooperates with the third limiting portion to limit the linear movement of the chamber cover.

[0015] In one embodiment, the chamber cover is provided with a sight line, which is located on the outside of the chamber cover away from the elastic cartridge case, and the sight line is arranged at the same horizontal plane as the barrel passage.

[0016] In this invention, an elastic cartridge case is connected to a sleeve, with the opening of the cartridge case communicating with the barrel passage of the sleeve. The cross-sectional area of ​​the barrel passage gradually decreases from the end near the elastic cartridge case to the end away from it. During use, the microparticle ammunition falls into the elastic cartridge case through the barrel passage. The user pinches the cartridge case containing the microparticle ammunition and pulls it away from the sleeve, generating elastic deformation. Upon release, the elastic potential energy of the cartridge case is converted into kinetic potential energy, propelling the microparticle ammunition towards the barrel passage. The barrel passage is designed to be narrower at the front and wider at the back, reducing resistance within the passage and fully releasing the inertia of the microparticle ammunition. The microparticle ammunition hits the insect through the barrel passage, thus completing the insect extermination process. Attached Figure Description

[0030] This utility model proposes an insecticidal gun.

[0031] See also Figure 3 and Figure 4 In one embodiment of this utility model, the insecticidal gun 100 includes:

[0032] Gun body 8, with a sleeve 2 inside the gun body 8, and the sleeve 2 having a barrel passage 2a;

[0033] Elastic cartridge 1 is fitted onto one end of sleeve 2. The inner cavity of elastic cartridge 1 is connected to the barrel passage 2a. The cross-sectional area of ​​the barrel passage 2a gradually decreases from the end near elastic cartridge 1 to the end away from elastic cartridge 1.

[0034] The gun body 8 is the main body and mounting base of the insecticide gun 100. It is made of plastic or metal materials to ensure overall stability and durability.

[0035] Sleeve 2 is a tubular structure inside the gun body 8, which has a chamber passage 2a inside.

[0036] The elastic cartridge 1 is fitted onto one end of the sleeve 2, and its inner cavity is connected to the bore passage 2a. The elastic cartridge 1 is made of a highly elastic material, such as rubber, which can produce elastic deformation when the user applies force, and convert the stored elastic potential energy into kinetic energy when released, thereby propelling the micro-particle ammunition out at high speed.

[0037] In this embodiment, the user loads particulate matter, such as salt or sand, into the magazine 4 of the insecticide gun 100. The magazine 4 is connected to the bore passage 2a. Under gravity, the particulate matter first falls into the bore passage 2a. The user holds the insecticide gun 100 vertically, at which point the elastic cartridge 1 is closest to the ground, causing the particulate matter to fall from the bore passage 2a into the elastic cartridge 1. The user pinches the elastic cartridge 1, applying a pulling force away from the sleeve 2, causing the elastic cartridge 1 to undergo elastic deformation, thereby storing elastic potential energy. When the user releases the elastic cartridge 1, the elastic potential energy within it is rapidly converted into kinetic energy, propelling the particulate matter out at high speed along the bore passage 2a, accurately killing the target insect.

[0038] See also Figure 1 and Figure 3 and Figure 6 In one embodiment of the present invention, the insecticidal gun 100 further includes a connecting ring 3, which connects the sleeve 2 and the elastic cartridge 1. A limiting boss 31 is formed at the end of the connecting ring 3 away from the sleeve 2. The elastic cartridge 1 is sleeved on the limiting boss 31, and part of the structure of the elastic cartridge 1 is clamped and limited between the limiting boss 31 and the sleeve 2.

[0039] Connecting ring 3 is a ring-shaped connector made of plastic or metal, designed to provide a stable mechanical connection.

[0040] The limiting boss 31 is a protruding part designed for one end of the connecting ring 3. The diameter of the limiting boss 31 is larger than the opening diameter of the elastic bladder 1, so that the elastic bladder 1 can be stably fitted onto the limiting boss 31.

[0041] The elastic cartridge 1 is fixed on the connecting ring 3 by the limiting boss 31 of the connecting ring 3, ensuring that the elastic cartridge 1 maintains the correct position and orientation when firing particulate ammunition.

[0042] A series of evenly distributed slots are designed on the outer edge of the connecting ring 3 for locking.

[0043] The inner edge of the sleeve 2 is designed with corresponding protruding buckles. These buckles are retractable metal springs that can be inserted into the slots during connection.

[0044] In this embodiment, during assembly, the elastic cartridge 1 is fitted onto the limiting boss 31, ensuring the alignment of the connecting ring 3 and the sleeve 2, so that the position of the slot corresponds to the position of the protruding buckle. The connecting ring 3 is then inserted into the sleeve 2, and the metal spring is locked in the slot. At this time, the limiting boss 31 and the sleeve 2 together clamp the elastic cartridge 1, making the connection of the elastic cartridge 1 more stable. This completes the connection and installation of the elastic cartridge 1, the connecting ring 3, and the sleeve 2. After assembly, necessary functional tests are performed, such as slight rotation or pulling, to verify the stability and reliability of the connection. During disassembly, the connecting ring 3 is pulled with one hand, and the sleeve 2 is pulled with the other hand to separate the connecting ring 3 from the sleeve 2.

[0045] This design enhances the stability of the elastic cartridge 1 while providing a reliable locking mechanism to prevent accidental separation during use, ensuring ease of operation and safety of use.

[0046] See also Figure 1 and Figure 3 and Figure 6 In one embodiment of this utility model, the end of the connecting ring 3 away from the elastic bladder 1 is provided with an external thread, and the end of the sleeve 2 near the elastic bladder 1 is provided with an internal thread. The connecting ring 3 is screwed to the sleeve 2 through the cooperation of the external thread and the internal thread.

[0047] In this embodiment, during assembly, the elastic cartridge 1 is fitted onto the limiting boss 31, and the external thread of the connecting ring 3 is aligned with the internal thread of the sleeve 2, ensuring correct thread alignment. The connecting ring 3 is rotated clockwise, causing its external thread to gradually engage with the internal thread of the sleeve 2 until the required tightness is achieved. At this point, the limiting boss 31 and the sleeve 2 together clamp the elastic cartridge 1. The stability of the connection is checked to ensure there are no signs of loosening or over-tightening. When disassembling the connecting ring 3 and the sleeve 2, the connecting ring 3 is rotated counterclockwise, causing the external thread to gradually disengage from the internal thread. During disassembly, care should be taken to avoid damaging the threads.

[0048] The threaded connection provides strong fastening force, making the connection between the connecting ring 3 and the sleeve 2 very stable, reducing accidental loosening caused by vibration or impact during the use of the insecticide gun 100.

[0049] Figure 1 and Figure 3 and Figure 4 In one embodiment of the present invention, the insecticidal gun 100 further includes an annular member 5. The sleeve 2 has a first limiting part 21 on the outside of one end near the elastic cartridge 1. The first limiting part 21 is adapted to the annular member 5. The annular member 5 is sleeved on the elastic cartridge 1 and is located on the first limiting part 21 so that the elastic cartridge 1 and the sleeve 2 are fastened together.

[0050] The annular component 5 is a ring-shaped structure, typically made of rubber, plastic, or other flexible materials, possessing good elasticity and wear resistance. The inner diameter of the annular component 5 is smaller than the outer diameter of the sleeve 2, allowing it to fit tightly onto the elastic bladder 1 mounted on the sleeve 2.

[0051] The first limiting part 21 is the external structure of the sleeve 2 near the end of the elastic bladder 1, and is usually one or more annular grooves used to limit the annular part 5.

[0052] In this embodiment, firstly, the elastic cartridge 1 is fitted onto the sleeve 2, ensuring that the opening of the elastic cartridge 1 is aligned with the bore passage 2a of the sleeve 2. Next, the annular member 5 is fitted onto the elastic cartridge 1 and slid along the elastic cartridge 1 until the edge of the annular member 5 matches the annular groove on the sleeve 2. When the edge of the annular member 5 aligns with the first limiting part 21, the annular member 5 is locked in place by the annular groove, thereby achieving a secure connection between the elastic cartridge 1 and the sleeve 2.

[0053] The annular groove, acting as the first limiting part 21, provides a clear stopping point, ensuring that the annular member 5 will not slide or shift on the elastic cartridge 1. Furthermore, the flexibility of the annular member 5 allows it to adapt to elastic cartridges 1 of different sizes, increasing the versatility and adaptability of the design.

[0054] See also Figure 1 and Figure 3 and Figure 4 In one embodiment of this utility model, the annular member 5 is a rubber ring.

[0055] In this embodiment, the rubber ring has good flexibility, easily adapting to elastic cartridges 1 of different sizes, unlike rigid connectors which require customization or specific dimensions. Furthermore, the elasticity of the rubber ring provides the necessary stretch during insertion and removal, facilitating user operation while maintaining a tight connection. If metal clips or adhesive bonding were used, the metal clips would be insufficiently flexible, difficult to adapt to elastic cartridges 1 of different sizes, and too costly and heavy; while adhesive bonding requires a certain curing time, making it unsuitable for rapid assembly and disassembly.

[0056] In summary, the rubber ring, as a connecting component, provides advantages in terms of flexibility, cost-effectiveness, corrosion resistance, and shock absorption in the design of the insecticide gun 100, while avoiding some common problems of other connecting methods.

[0057] See also Figure 1 and Figure 2 and Figure 3 In one embodiment of the present invention, the insecticidal gun 100 further includes a magazine 4, which has a transparent observation section.

[0058] The transparent viewing section is made of plastic, which can withstand wear and impact during daily use and is not easily damaged.

[0059] In this embodiment, the transparent observation section allows users to directly see the remaining ammunition in the magazine 4 without opening the magazine 4 or performing any additional operations, providing a convenient and intuitive monitoring method. Because the remaining ammunition is clearly visible, users can reduce errors caused by guessing the ammunition level, such as reloading or attempting to fire when ammunition is depleted.

[0060] See also Figure 1 and Figure 2 and Figure 3 In one embodiment of this utility model, the gun body 8 further includes a chamber cover 6 and a grip 7, the chamber cover 6 and the grip 7 forming a first cavity 6a; the magazine 4 is partially disposed in the first cavity 6a, the magazine 4 forming a second cavity 4b and a second through hole 4a, the second through hole 4a extending into the first cavity 6a, the sleeve 2 forming a first through hole 2b, and the barrel passage 2a communicating with the first through hole 2b; in the initial state of the insecticide gun 100, the second through hole 4a and the first through hole 2b are isolated; in the loaded state of the insecticide gun 100, the second through hole 4a, the first through hole 2b and the barrel passage 2a are connected in sequence.

[0061] In this embodiment, the user first checks the ammunition level in the magazine 4 to ensure there is enough ammunition for firing. The user pulls the chamber cover 6 backward with one hand while gripping the handle 7 with the other. At this time, the sleeve 2 is fixed to the handle 7 and does not move with the chamber cover 6. As the chamber cover 6 is pulled, the magazine 4 slides relative to the sleeve 2. At this time, the second through hole 4a of the magazine 4 aligns with the first through hole 2b of the sleeve 2, allowing the ammunition in the magazine 4 to enter the chamber passage 2a under the action of gravity, verticalizing the insecticide gun 100, ready to fire. After the ammunition is loaded, the user pushes the chamber cover 6 forward to return it to its original position, disconnecting the second through hole 4a from the first through hole 2b, ensuring that the chamber passage 2a is isolated from the magazine 4.

[0062] The relative sliding mechanism between the chamber cover 6 and the sleeve 2 ensures smooth ammunition loading and a sealed chamber, improving firing accuracy and reliability. Users can easily load and fire ammunition while ensuring operational safety and convenience.

[0063] See also Figure 1 and Figure 3 and Figure 5 In one embodiment of this utility model, the magazine 4 is provided with a magazine 4c at one end near the second through hole 4a, the sleeve 2 has a stepped partition piece 22, the magazine 4c is vertically connected to the second through hole 4a, the magazine 4c is provided with a third through hole 4d in the horizontal direction, and the stepped partition piece 22 can be inserted into the third through hole 4d; the magazine 4c connects the second cavity 4b and the second through hole 4a.

[0064] The magazine 4c is located at one end of the magazine 4 near the second through hole 4a. The magazine 4c is vertically connected to the second through hole 4a, allowing the particulate ammunition to flow from the magazine 4 into the chamber passage 2a under the influence of gravity. The magazine 4c has a third through hole 4d in the horizontal direction, which is used to accommodate the insertion of the stepped partition plate 22.

[0065] The sleeve 2 has a stepped partition 22, which can be inserted into the third through hole 4d when needed, thereby cutting off the communication between the spring slot 4c and the second cavity 4b.

[0066] Preferably, the sleeve 2 is further provided with a baffle guide groove 2c at one end near the magazine 4. The bottom end of the dispensing groove 4c abuts against the baffle guide groove 2c, and the dispensing groove 4c can move linearly within the baffle guide groove 2c. The baffle guide groove 2c is positioned opposite to the stepped partition plate 22. The dispensing groove 4c includes an extension section 41, which extends from both sides of the dispensing groove 4c toward the chamber direction. The extension section 41 abuts against both sides of the stepped partition plate 22 to prevent particulate ammunition from leaking from both sides of the stepped partition plate 22.

[0067] Initially, the second cavity 4b, the magazine 4, the magazine slot 4c, and the second through hole 4a are connected, and the particulate ammunition is stored in these spaces. When the user loads the magazine, the stepped partition 22 of the sleeve 2 is inserted into the third through hole 4d by operating the chamber cover 6, isolating the magazine slot 4c and the second cavity 4b, while simultaneously connecting the second through hole 4a with the first through hole 2b. At this time, the particulate ammunition in the magazine slot 4c falls into the chamber passage 2a through the first through hole 2b under the influence of gravity, ready to be fired.

[0068] See also Figure 1 and Figure 5 In one embodiment of the present invention, the chamber cover 6 has a second limiting part 61, the grip 7 has a first fixing part 71, the first fixing part 71 has a third limiting part 711, the sleeve 2 is connected to the first fixing part 71, and the second limiting part 61 and the third limiting part 711 cooperate to limit the linear movement of the chamber cover 6.

[0069] The second limiting part 61 is a protrusion designed on the chamber cover 6. This protrusion can be cylindrical or square and is used to mate with the groove of the third limiting part 711 on the grip 7.

[0070] The first fixing part 71 is a fixing structure designed inside the grip 7 to fix the sleeve 2 and provide stable support.

[0071] The third limiting part 711 and the first fixing part 71 are provided with a strip-shaped groove. This groove extends along the grip 7 towards the muzzle and is used to guide the protrusion on the chamber cover 6 to achieve linear movement.

[0072] Preferably, the chamber cover 6 has a baffle that surrounds one end of the sleeve 2 away from the elastic cartridge 1. A spring is fitted onto the end of the first fixing part 71 near the muzzle of the insecticide gun 100, with both ends of the spring abutting against the baffle and the first fixing part 71, respectively. When the user loads the cartridge, the baffle applies pressure to the spring, converting kinetic potential energy into elastic potential energy, and the spring is compressed. When the user releases the cartridge, the elastic potential energy of the spring is converted into kinetic potential energy, causing the chamber cover 6 to return to its original position. Considering that the salt particles used as particulate ammunition are prone to moisture absorption, forming large lumps of salt that can become stuck in the connection between the cartridge and the chamber passage, the vibration generated when the chamber cover returns to its original position can shake the salt particles, allowing them to fall smoothly into the chamber passage.

[0073] In this embodiment, the protrusion on the bore cover 6 is correctly installed and aligned with the groove on the grip 7. The size of the groove is adjusted to ensure a tight fit with the protrusion on the bore cover 6. During the user's loading and unloading of the bore cover 6, the protrusion slides within the groove. The engagement between the protrusion and the groove not only enables linear sliding but also limits the movement distance of the bore cover 6, ensuring that the bore cover 6 does not exceed its design range during loading and unloading.

[0074] See also Figure 1 and Figure 3 In one embodiment of this utility model, the chamber cover 6 is provided with an aiming line 62. The aiming line 62 is located on the outside of the chamber cover 6 away from the elastic cartridge 1, and the aiming line 62 is arranged at the same horizontal plane as the barrel passage 2a.

[0075] The aiming line 62 is level with the bore passage 2a, ensuring muzzle stability and accurate aiming for the user. Furthermore, to provide greater aiming flexibility, the aiming line 62 is not only located on one side of the bore cover 6, but also on both sides. This design offers users two aiming directions, allowing them to choose the most suitable aiming line 62 based on the actual usage scenario and personal preference. Whether left-handed or right-handed, users can find an aiming method that suits them, thereby improving shooting comfort and accuracy.

[0076] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
