Description

Technical Field

[0001] This disclosure relates to the field of insect control equipment, and more particularly to an insect control device. Background Technology

[0002] Insecticides, as a common hygiene tool, are widely used in homes, yards, farms and other places. They kill pests such as mosquitoes and flies by spraying fine sand, salt, toxic powder or liquid.

[0003] US Patent No. 8251051B2 discloses a mosquito-killing gun that uses beads of materials such as fine sand and salt as projectiles, which are then ejected by high-pressure gas to physically kill mosquitoes and flies. However, when using this mosquito-killing gun, the user needs to manually load the gun, manually release the safety, and finally pull the trigger before each shot; the same operation needs to be repeated for each subsequent shot, making it cumbersome, inconvenient, and inefficient.

[0004] To address the aforementioned issues, although electric insect-killing guns have been disclosed in related technologies, their drive mechanisms are primarily used to replace manual compressed air, improving single-shot efficiency to some extent. However, during continuous firing, the overall firing efficiency still needs improvement. Summary of the Invention

The interval between two adjacent shots can be shortened to about 800 milliseconds, which significantly improves the efficiency of continuous firing and the hit rate against fast-moving targets.

[0027] Furthermore, the operation process is greatly simplified. Users only need to operate the firing mechanism (such as the trigger) to complete the entire cycle from firing to being ready to fire again, simplifying the traditional manual insect killer's "firing-manual loading-firing again" mode to a "firing-automatic reset-firing again" mode, greatly reducing the operational burden.

[0041] In the field of physical pest control equipment, especially electric pest killers, improving pest control efficiency has always been one of the core objectives. To achieve effective pest control, the equipment usually needs to be able to fire rapidly and continuously to cope with the movement of mosquitoes and other moving targets and the need for multiple strikes.

[0042] To achieve the above goals, there are two main types of solutions in the relevant technologies. One type is a purely manual mechanical solution, which relies entirely on the user's manual operation to complete the series of actions of loading, unlocking the safety, and pulling the trigger. The entire operation chain must be repeated before each shot, and the manual steps cannot be omitted. The other type is a solution that improves upon this by electrification, which usually uses an electric drive mechanism to replace the manual loading action. However, the drive control logic of this type of solution is often relatively simple. For example, it may only perform a single charge upon receiving the user's loading command, or after completing a single shot, the drive mechanism needs to undergo a reset or waiting process before it can begin preparing for the next shot.

[0043] The aforementioned solutions, due to their inherent operational logic or control timing, inevitably involve waiting intervals or additional user operation steps during the cycle from the completion of one shot to preparation for the next. This results in a bottleneck in improving overall shooting efficiency, making it difficult to achieve rapid continuous firing. With users' increasing demand for convenient and efficient pest control, how to shorten the preparation time between consecutive shots and reduce user intervention, thereby substantially improving the continuous firing efficiency and user experience of electric pest killers while ensuring safety, has become an urgent technical problem to be solved.

[0044] The technical solutions of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments.

[0045] See Figure 1 and Figure 2 This disclosure provides an insect killer. The insect killer mainly includes a housing 1, an energy storage unit 2, a drive mechanism, a firing element 4, a projectile loading mechanism 5, a control unit 7, and a launching tube 8.

[0046] The housing 1 is gun-shaped and can be assembled from a rear cover 11, a gun body, and a head shell 13. The gun body is formed by joining a left housing 121 and a right housing 122 together, and its interior is used to house various functional modules. The left housing 121 and the right housing 122 can be fixedly connected by screws or snap-fit.

[0047] The launching tube 8 is located at the front of the housing 1 and is used to guide the projectile out of the shell. The projectile can be salt grains, fine sand, or other solid particles. The launching tube 8 has a first direction along the launching direction (i.e., the direction shown by arrow a in the figure) and a second direction opposite to the launching direction (i.e., the direction shown by arrow b in the figure).

[0048] The energy storage unit 2 stores the energy required to fire the projectile; the drive mechanism drives the energy storage unit 2 into the energy storage state; the firing element 4 is operated by the user to issue a firing command; the projectile loading mechanism 5 supplies the projectile to the firing tube 8; and the control unit 7 coordinates the timing of the actions of each mechanism to achieve an automated firing cycle. Specifically, the control unit 7 is configured to: respond to the firing command issued by the firing element 4, control the energy storage unit 2 to release energy to complete the projectile firing; after the energy storage unit 2 releases energy, automatically control the drive mechanism to drive the energy storage unit 2 back into the energy storage state and maintain it, so that the insect killer automatically returns to the ready-to-fire state.

[0049] The following describes a basic embodiment of this disclosure, which focuses on demonstrating the layout of the core components and the basic working principle of the insect killer.

[0050] refer to Figure 2 and Figure 6 The energy storage unit 2 is disposed within the housing 1 and includes a cylinder 21, a reciprocating piston, and an energy storage component 23 that applies a force in a first direction to the piston. The cylinder 21 has an outlet at its front end, which communicates with the launch tube 8. The cylinder 21 and the launch tube 8 are coaxially arranged. The piston includes a piston 221 and a piston rod 222. The piston rod 222 slides through the cylinder 21, and the piston 221 is fixedly disposed at one end of the piston rod 222 located within the cylinder 21. In this embodiment, the energy storage component 23 is a compression spring sleeved on the piston rod 222. One end of the compression spring abuts against the cylinder 21, and the other end acts on the flange of the piston 221 or the piston rod 222, constantly applying a forward thrust, i.e., a force in the first direction, to the piston.

[0051] In this application, "energy storage unit 2" refers to any component capable of storing energy and firing upon release. For example, it may include, but is not limited to, a structure comprising a reciprocating piston and an energy storage component 23 applying a firing direction force to the piston; or a combination of a spring and a cylinder. "Energy storage state" may refer to the state in which the energy storage component 23 is compressed or stretched to store potential energy.

[0052] refer to Figures 2 to 4 The drive mechanism includes a drive source 31 and a transmission assembly 32. The drive source 31 is fixed inside the housing 1 and can be an electric motor, but is not limited to this; it can also be other types of power sources such as pneumatic motors, hydraulic motors, etc.

[0053] The transmission assembly 32 is connected between the output shaft of the drive source 31 and the piston rod 222, and is used to convert the rotational motion of the drive source 31 into the linear motion of the piston rod 222. The transmission assembly 32 has a switchable first state and a second state. In the first state, the transmission assembly 32 can transmit the power of the drive source 31 to the piston to drive it to move in the second direction, so that the energy storage unit 2 enters the energy storage state, and can lock the energy storage unit 2 after energy storage is completed. In the second state, the transmission assembly 32 releases the lock on the energy storage unit 2.

[0054] refer to Figure 2 and Figure 5 The firing element 4 includes a trigger 41, which is slidably disposed in the grip portion 14 of the housing 1. The control unit 7 can be a circuit board with a microcontroller, electrically connected to the drive source 31, and receives firing commands from the firing element 4. A micro switch 42 electrically connected to the control unit 7 is disposed inside the housing 1; when the trigger 41 slides to touch the micro switch 42, the micro switch 42 issues a firing command. A second reset element 43 is disposed inside the housing 1, which can be a reset spring, allowing the trigger 41 to slide towards or away from the hopper 51. Specifically, when the user pulls the trigger 41, the trigger 41 slides away from the hopper 51 (i.e., backward); when the user releases the trigger 41, the trigger 41 resets towards the hopper 51 (i.e., forward) under the action of the trigger 41 reset spring.

[0055] In this application, "firing element 4" refers to any component used to issue a firing command. For example, it may include, but is not limited to, a trigger 41, a button, or a sensor switch; or a mechanical structure linked to a micro switch 42. "Firing command" refers to any signal that instructs the insect killer to perform a firing action. For example, it may include, but is not limited to, an electrical signal triggered by the firing element 4; or a user operation signal detected by a sensor.

[0056] According to the above structure, the insect killer's initial, factory-shipped, or ready-to-fire state is as follows: the drive mechanism pulls the piston rod 222 backward via the transmission assembly 32, compressing the energy storage component 23. Simultaneously, the piston 221 moves backward, increasing the volume of the front chamber of the cylinder 21, allowing outside air to enter the front chamber. The energy storage component 23 is compressed, and the energy storage unit 2 completes energy storage. At this time, the transmission assembly 32 remains in the power transmission state (first state), overcoming the thrust of the energy storage component 23 and locking the piston in the rear energy storage position. When the user pulls the firing button 4, the firing command is sent to the control unit 7. In response to the firing command, the control unit 7 controls the drive source to start, controls the transmission assembly 32 to exit the power transmission state, and enters the second state. Once the transmission connection is released, the elastic potential energy stored in the energy storage component 23 is immediately released, pushing the piston 221 forward at high speed (first direction), rapidly compressing the air in the front chamber of the cylinder 21, generating a high-pressure airflow. This high-pressure airflow propels the projectile, already in the firing position, out at high speed through the air outlet and the firing tube 8, completing the firing. Once the drive source drives the transmission assembly 32 into the first state, the power transmission state is restored. The drive source 31 drives the piston rod 222 to move backward again through the transmission assembly 32 until it returns to the energy storage position and is locked again. The energy storage element 23 is compressed again, completing the re-energy storage process. This allows the insect killer to automatically return to the ready-to-fire state without any manual intervention, preparing it for the user's next shot and significantly shortening the interval between continuous firing.

[0057] In this application, "control unit 7" refers to any electronic control module configured to respond to firing commands and control the energy storage unit 2 to release energy and automatically restore energy. For example, it may include, but is not limited to: microcontrollers, programmable logic controllers, or application-specific integrated circuits; or circuit boards electrically connected to the drive mechanism and position detection unit.

[0058] It is understandable that the specific implementation methods of the above energy storage and transmission solutions are not unique. (Reference) Figure 6 and Figure 7 In another embodiment, a detailed scheme is provided regarding the pneumatic structure of the energy storage unit 2 and the self-locking function of the transmission assembly 32. The cylinder 21, piston 221, and piston rod 222 structures of this embodiment are similar to those of the basic embodiment, but the piston 221 has been optimized to improve aerodynamic efficiency.

[0059] Specifically, a first limiting part 2211 and a second limiting part 2212 are fixedly provided on the piston 221, with the first limiting part 2211 being closer to the piston rod 222 than the second limiting part 2212. A sealing ring 223 is slidably fitted onto the piston 221 along its axial direction, located between the first limiting part 2211 and the second limiting part 2212. The sealing ring 223 can be made of rubber or metal. To allow the sealing ring 223 to slide freely on the surface of the piston 221, the surface of the piston 221 or the sealing ring 223 should be as smooth as possible to reduce friction. For example, a polytetrafluoroethylene layer can be provided on the surface of the piston 221. The first limiting part 2211 and the second limiting part 2212 can be an annular boss structure or other structures, mainly used to limit the sliding range of the sealing ring 223.

[0060] A gas chamber 224 is provided on the end face of the piston 221 away from the piston rod 222, and a gas hole 225 communicating with the gas chamber 224 is provided on the side wall of the piston 221. The number of gas holes 225 can be one or more.

[0061] In one embodiment, a gas passage 226 is provided between the first limiting part 2211 and the inner wall of the cylinder 21 for gas passage. This gas passage 226 is essentially the gap between the first limiting part 2211 and the inner wall of the cylinder 21. In another embodiment, the gas passage 226 is provided on the first limiting part 2211. The gas passage 226 can be a through hole extending axially through the first limiting part 2211 along the cylinder axis, or a slot formed on the side wall of the first limiting part 2211 away from the center of the piston 221. In other embodiments, gas passages 226 are provided both between the first limiting part 2211 and the inner wall of the cylinder 21, and also on the first limiting part 2211 itself.

[0062] When the sealing ring 223 abuts against the second limiting part 2212, the vent 225 is at least partially located outside the sealing ring 223, meaning the width of the sealing ring 223 is less than the distance from the second limiting part 2212 to the vent wall away from the second limiting part 2212. This prevents the sealing ring 223 from completely sealing the vent 225, allowing the front and rear chambers of the piston 221 to communicate with each other. Furthermore, the width of the sealing ring 223 is less than the distance from the second limiting part 2212 to the vent 225, allowing the vent 225 to be fully open, improving the efficiency of air from the rear chamber entering the front chamber through the vent 225.

[0063] When the drive mechanism drives the piston to move backward to store energy, the piston 221 moves backward relative to the cylinder 21. At this time, due to gas resistance and friction with the cylinder wall, the sealing ring 223 moves in the first direction relative to the piston 221 under the action of inertia or air pressure difference, that is, forward, and abuts against the second limiting part 2212. In this state, the air hole 225 is at least partially located outside the sealing ring 223, that is, exposed between the sealing ring 223 and the first limiting part 2211. The air in the rear cavity of the piston 221 can smoothly pass through the air passage 226 between the first limiting part 2211 and the cylinder wall, and then enter the front cavity of the cylinder 21 through the air hole 225, realizing rapid inflation and reducing inflation resistance. When energy storage is completed, after the transmission assembly 32 locks the piston, the piston is in a stationary energy storage position.

[0064] When the firing command is triggered, the transmission assembly 32 releases the piston, and the energy storage unit 23 pushes the piston 221 forward at high speed. In the initial instant of this rapid forward thrust, the sealing ring 223 tends to remain relatively stationary due to inertia, or, under the pressure of the gas in front, quickly comes into contact with the first limiting part 2211. At this time, the sealing ring 223 slides tightly against the inner wall of the cylinder 21 under the push of the piston 221, and the sealing ring 223 and the inner wall of the cylinder 21 are in sealed contact, preventing the gas in the front chamber from entering the rear chamber of the cylinder 21. This creates a sealed space in the front chamber of the cylinder 21, which is rapidly compressed as the piston 221 moves forward. The resulting high-pressure gas cannot leak backward, i.e., it cannot pass over the sealing ring 223 to enter the rear chamber of the cylinder. All the high-pressure gas is used to propel the projectile, thus achieving efficient sealing and full energy release during firing. The term "high-pressure gas" here refers to gas in a compressed state, with a pressure greater than that of uncompressed gas. For example, when releasing energy, the gas in the front chamber is in a compressed state, with a pressure greater than that of the rear chamber and the external air pressure of the launch tube 8. In other words, the air in the front chamber is high-pressure gas.

[0065] When the sealing performance of the sealing ring 223 weakens or fails due to long-term use or other reasons, a gap exists between the sealing ring 223 and the inner wall of the cylinder 21. To prevent air leakage from the vent 225 during energy release, high-pressure gas in the front cavity of the cylinder 21 enters the front cavity of the cylinder 21 through the vent 225 and the gap between the sealing ring 223 and the cylinder 21, resulting in "air leakage" and loss of energy used to launch the projectile.

[0066] Building upon the above example, further, when the sealing ring 223 contacts the first limiting portion 2211, the vent 225 is completely or partially sealed by the sealing ring 223. When the sealing ring 223 contacts the first limiting portion 2211, the vent 225 is completely sealed by the sealing ring 223, meaning the width of the sealing ring 223 is greater than the distance from the first limiting portion 2211 to the wall of the vent 225 away from the first limiting portion 2211.

[0067] In this embodiment, reference Figure 3 and Figure 4 The transmission assembly 32 includes a rack 321, an incomplete gear 322, and a self-locking assembly.

[0068] Specifically, rack 321 is fixedly mounted on piston rod 222 along its length. Incomplete gear 322 is rotatably mounted within housing 1, with its teeth distributed only on a portion of its circumference. The toothed portion meshes with rack 321, while the toothless portion disengages. When the toothed portion of incomplete gear 322 meshes with rack 321, transmission assembly 32 is in a first state (driving state); when the toothless portion of incomplete gear 322 rotates to a position opposite rack 321, the two disengage, and transmission assembly 32 exits the first state and enters a second state (disengaged state).

[0069] The input end of the self-locking assembly is connected to the drive source 31, and the output end is connected to the incomplete gear 322. In this embodiment, the self-locking assembly adopts a worm gear 323 and worm 324 mechanism. The worm gear 323 and worm 324 mechanism has a self-locking characteristic. When the drive source 31 stops, the worm gear 323 and worm 324 can prevent the incomplete gear 322 from reversing under the action of external force (such as the force applied by the energy storage spring through the rack 321), thereby reliably locking the piston in the energy storage position.

[0070] It is understood that the aforementioned structure of "incomplete gear 322 + rack 321" is only one specific implementation of the transmission component 32. Any transmission component 32 that can switch between two states—"drive source 31 drives piston 221 to store energy" and "piston 221 disengages from drive source 31 and fires freely"—is within the scope of this invention. For example, the transmission component 32 can also employ an electromagnetic clutch (using an electromagnet to control the connection and disconnection of power), a ratchet and pawl mechanism, a cam mechanism, etc.

[0071] Further reference Figures 2 to 4 To reduce the output torque of the drive source 31, such as a motor, the drive mechanism also includes a speed reducer. The speed reducer includes a housing 326 and a reduction gear set 325 rotatably disposed within the housing 326. A worm gear 323 and worm 324 mechanism can be disposed at either the input or output end of the reduction gear set 325. In this embodiment, the output shaft of the drive source 31 is fixedly connected to the worm 324, the worm gear 323 is connected to the input end of the reduction gear set 325, and the worm gear 323 and worm 324 mesh. An incomplete gear 322 is fixedly disposed at the output end of the reduction gear set 325.

[0072] The output shaft of the drive source 31 is connected to the worm gear 324, which meshes with the worm wheel 323 to form the first stage of reduction and self-locking. The output of the worm wheel 323 is further reduced in speed and increased in torque by the reduction gear set 325, driving the incomplete gear 322 to rotate. The rack 321 is fixedly mounted on the piston rod 222 along its length. The teeth of the incomplete gear 322 mesh with the rack 321. When the drive source 31 drives the incomplete gear 322 to rotate clockwise, its teeth push the rack 321 and the piston rod 222 to move backward in a straight line, completing energy storage. Due to the inherent self-locking characteristic of the worm gear 323 and worm 324 mechanism, when the drive source 31 stops supplying power, the torque from the energy storage component 23 attempting to reverse-drive the worm 324 via the rack 321, incomplete gear 322, gear set 325, and worm gear 323 cannot overcome the frictional self-locking angle between the worm 324 and the worm gear 323. This effectively prevents the piston from accidentally moving forward and releasing energy in the energy storage state. This ensures the safety and stability of the equipment in the ready-to-fire state.

[0073] Furthermore, in order to precisely control the stopping position of the piston during the automatic re-energy storage process, the insect killer disclosed herein also includes a position detection unit, which is used to detect whether the piston has reached the energy storage position and output a position detection signal when it has reached the position.

[0074] In this embodiment, reference Figure 2 and Figure 6 The position detection unit includes a magnetic element 91 and a Hall sensor 92 that cooperate with each other. The magnetic element 91 (such as a magnet) is disposed on the piston rod 222, specifically on the top wall of the piston rod 222 near the end of the incomplete gear 322. The Hall sensor 92 is disposed on or electrically connected to the circuit board, and its installation position corresponds to the position of the magnetic element 91 when the piston moves to the energy storage position, and can be directly opposite each other vertically.

[0075] When the drive mechanism drives the piston rod 222 backward to recharge energy, the magnetic element 91 moves backward along with the piston rod 222. When the piston reaches the preset energy storage position, the magnetic element 91 moves precisely below the sensing area of ​​the Hall sensor 92. The Hall sensor 92 detects the change in magnetic field and generates and sends a high-level or low-level position arrival signal to the control unit 7. The control unit 7 responds to the signal and immediately controls the drive source 31 to stop. Because the transmission assembly 32 has a self-locking function, after the drive source 31 stops, the piston is precisely locked at the energy storage position, which avoids mechanical impact or mechanism interference caused by overshoot and ensures the consistency of the energy storage state each time, thereby ensuring stable firing power.

[0076] It is understood that the position detection unit is not limited to the Hall sensor 92; it can also employ photoelectric sensors (detecting position by blocking or reflecting light), microswitches (triggered by mechanical contact), potentiometers (detecting position by changes in resistance), etc. Any component or combination capable of detecting whether the piston has reached the energy storage position is acceptable.

[0077] Optionally, refer to Figure 8 and Figure 9 The insect killer also includes a projectile loading mechanism 5, which is used to load projectiles into the firing tube 8. This embodiment aims to achieve automatic projectile loading and synchronization with the firing action. The projectile loading mechanism 5 mainly includes a hopper 51, a feeding rod 52, and a linkage assembly.

[0078] The hopper 51 is used to hold multiple projectiles, and its bottom is fixedly mounted above the inlet of the launch tube 8 via the base 54. The launch tube 8 has a mounting through hole 81 in a vertical or approximately vertical direction, and the inlet is the upper opening of the mounting through hole 81. The vertical direction here is the z-direction in the figure.

[0079] The feed rod 52 slides vertically or nearly vertically through the mounting through-hole 81 at the bottom of the hopper 51 and on the side wall of the launching tube 8. A feed hole 521 is provided on the feed rod 52, which is positioned along the length of the launching tube 8. This feed hole 521 communicates with the inner cavity of either the hopper 51 or the launching tube 8 when the feed rod 52 slides to different heights. When the feed hole 521 is connected to the hopper 51, the projectiles in the hopper 51 fall into and fill the feed hole 521 under gravity; when the feed hole 521 is connected to the launching tube 8, the projectiles in the feed hole 521 fall into the launching tube 8, completing one loading cycle.

[0080] The linkage component is connected between the firing member 4 and the material take-up rod 52. In this embodiment, the linkage component includes a first reset member 531 and a pulling component.

[0081] The first reset member 531 is connected to the picking rod 52 and is used to drive the picking rod 52 to move upward and reset so that the picking hole 521 is located inside the hopper 51. The first reset member 531 may be a spring, sleeved on the picking rod 52, with one end abutting against the flange 522 on the picking rod 52 and the other end abutting against the housing 1.

[0082] The pulling assembly is connected to the trigger 41 and the take-up bar 52, respectively. In this embodiment, the pulling assembly includes a pull rod 5321 and a connecting rod 5322. The connecting rod 5322 is hinged inside the housing 1 (e.g., mounted on a support on the housing 1 via a pin). One end of the connecting rod 5322 is hinged to the take-up bar 52, and the other end is hinged to the pull rod 5321. The end of the pull rod 5321 away from the connecting rod 5322 is connected to the trigger 41. In this embodiment, as... Figure 8As shown, the pull rod 5321 and the trigger 41 are connected by a snap-fit ​​mechanism. For example, one end of the pull rod 5321 is provided with a locking block, and the trigger 41 is provided with a locking groove; or the pull rod 5321 is provided with a locking groove, and the trigger 41 is provided with a locking block. The connection and fixation are achieved by the engagement of the locking block and the locking groove, which is convenient for installation. In other embodiments, a hinged or fixed connection can also be used, such as screw connection, welding, or glue bonding. No specific limitation is made here. Specifically, the connecting rod 5322 can be L-shaped in general. The section of the connecting rod 5322 that connects to the drive rod is provided with an oblong hole. An orthogonal rod 523 is fixedly provided on the material picking rod 52. The orthogonal rod 523 passes through the oblong hole to achieve a hinged connection.

[0083] The working process of the projectile loading mechanism 5 is as follows: When the user pulls the trigger 4, the trigger 4 slides backward. Pulling the lever 5321 causes the connecting rod 5322 to rotate around its fulcrum. The connecting rod 5322 drives the orthogonal rod 523 and the feed rod 52 to slide downward against the elastic force of the first reset member 531. The downward movement of the feed rod 52 causes the feed hole 521 to move from the hopper 51 area to a position aligned with the firing tube 8. At this point, the feed hole 521 is coaxial with the firing tube 8, and the projectile located in the feed hole 521 is also equivalent to being located inside the firing tube 8, completing the loading process. This loading process is completely synchronized with the pulling of the trigger 41, ensuring that the projectile is accurately positioned before the energy storage unit 2 releases energy. After firing, the user releases the trigger 4, which moves forward to reset under the action of its own second reset member 43 (reset spring). Simultaneously, the constraints of the linkage components are released, and the first reset component 531 pushes the feeding rod 52 upward to reset, allowing the feeding hole 521 to return to the hopper 51 to receive the next set of projectiles, preparing for the next firing. This mechanical linkage method requires no additional drive motor or control logic, has a simple and reliable structure, and ensures strict synchronization between feeding and firing actions.

[0084] Further reference Figure 8 and Figure 9 To prevent the material-receiving rod 52 from rotating and to ensure that the material-receiving hole 521 is coaxial with the launching tube 8, a positioning groove 541 is provided on the top of the base 54. The positioning groove 541 can be rectangular or other polygonal. A positioning seat 82 is fixedly installed on the launching tube 8, and the positioning seat 82 is adapted to the positioning groove 541. The cross-section of the positioning seat 82 can be rectangular or other polygonal. During installation, the positioning seat 82 is inserted into the positioning groove 541 to prevent the positioning seat 82 from rotating relative to the launching tube 8.

[0085] The base 54 has a vertically oriented through-hole 542 for the material-receiving rod 52 to pass through. The inner wall of the through-hole 542 has a positioning plane 5421, which is a vertical surface. One or more positioning planes 5421 can be provided. A positioning block 524 is fixedly mounted on the material-receiving rod 52 to cooperate with the positioning plane 5421. The surface of the positioning block 524 that contacts the positioning plane 5421 is flat. During projectile loading, the positioning block 524 remains at least partially in contact with the positioning plane 5421, ensuring that the material-receiving rod 52 is always constrained, preventing it from rotating around its own axis. This ensures that the axis of the material-receiving hole 521 is parallel or collinear with the axis of the launching tube 8, ensuring successful projectile launch.

[0086] Optionally, to prevent oversized or defective projectiles from entering the launch tube 8 and causing jamming, damage to the inner wall, or other hazards, refer to Figure 10 and Figure 11 A blocking part 513 is provided inside the hopper 51 of the projectile loading mechanism 5.

[0087] The blocking part 513 divides the inner cavity of the hopper 51 into a first region 511 and a second region 512. The first region 511 is characterized by the area between the blocking part 513 and the picking rod 52, and the second region 512 is characterized by the area between the blocking part 513 and the inner wall of the hopper 51. The picking hole 521 is located in the first region 511. The blocking part 513 is configured to allow only sized projectiles to enter the first region 511.

[0088] The blocking part 513 can be implemented in several ways: In one implementation, the blocking part 513 includes at least two vertically arranged baffles, spaced apart, extending upward from the bottom of the hopper 51. The projection of the feeding hole 521 along a first direction at least partially coincides with the baffle, meaning that light rays passing through the feeding hole 521 along the first direction illuminate the baffle, thus the baffle serves to block the feeding hole 521 and prevent the projectiles in the hopper 51 from bypassing the baffle and directly entering the feeding hole 521. Preferably, the width of the baffle is greater than the width of the feeding hole 521, and the feeding hole 521 is positioned directly opposite the center of the baffle.

[0089] The baffle has openings for only sized projectiles to pass through. These openings can be circular, rectangular, or other shapes, and their size cannot exceed the maximum size of the largest sized sized projectile. This effectively prevents unqualified projectiles from passing through.

[0090] In one example, a first gap is provided between the end of the baffle and the inner wall of the hopper 51. The distance of the first gap is d1, and the value of d1 is not greater than the maximum width of the largest qualified shot. The gap between the baffle and the inner wall of the hopper 51 allows the shot inside the hopper 51 to pass through this gap, i.e., the first gap, into the first region 511. Since the inner wall of the hopper 51 may not be a vertical plane, but may be an inclined surface that is wider at the top and narrower at the bottom, in this embodiment, the distance d1 is the minimum distance of the first gap. For the case where the inner wall of the hopper 51 is an inclined surface, d1 is the distance between the bottom of the baffle and the bottom of the hopper 51. Furthermore, the two sides of the baffle can be vertically arranged or inclined parallel to the inner wall of the hopper 51.

[0091] In one example, a second gap, denoted as d2, is provided between the ends of two adjacent baffles. The value of d2 is no greater than the maximum width of the largest acceptable projectile. Since the projectiles in the second region 512 of the hopper 51 need to pass through the first gap before entering the first region 511, this process is generally necessary. In this example, simply limiting the size of the second gap effectively prevents unacceptable projectiles from entering the first region 511. In this example, the distance between the ends of two adjacent baffles is equal at all height positions. That is, the ends of two adjacent baffles can both be vertical planes or inclined surfaces with the same direction of inclination, as long as the distance between them is equal.

[0092] In one example, a third gap, denoted as d3, is provided between the baffle and the picking rod 52. The value of d3 is no greater than the maximum width of the largest acceptable shot. The distance between the baffle and the picking rod 52 remains constant in the vertical direction; that is, the baffle is vertically positioned. Since the shot in the second region 512 of the hopper 51 needs to pass through the first gap, then the second gap, and then the third gap before entering the picking hole 521 to enter the first region 511, in this example, directly limiting the size of the third gap effectively prevents unacceptable shot from entering the first region 511.

[0093] Based on this, in another embodiment, it is possible to simultaneously limit the dimensions of the first gap and the second gap, or to choose not to limit the dimensions of the first gap and the second gap.

[0094] In another preferred design, refer to Figure 12 The blocking part 513 is a closed ring-shaped baffle that projects onto the horizontal plane. For example, it can be a circular baffle. The ring baffle is arranged around the material picking rod 52 and has multiple openings evenly provided on it for only qualified size projectiles to pass through.

[0095] Furthermore, the height of the baffle is less than the depth of the hopper 51, meaning the top of the baffle is lower than the top of the hopper 51. When projectiles are fed from the top of the hopper 51, some projectiles may directly enter the first area 511. Therefore, to prevent defective projectiles from entering the first area 511 during the projectile feeding process, the distance between the baffle and the feeding hole 521 needs to be limited, which can also be understood as the distance between the baffle and the feeding rod 52. This distance is not greater than the maximum width of the largest qualified projectile, because several projectiles may not be of equal size, and the projectiles may not be spherical or other regular shapes; therefore, it is necessary to limit the maximum width of the largest qualified projectile. It can be understood that the above-mentioned qualified projectiles refer to those whose size is less than a certain value, which can be considered qualified projectiles; conversely, those whose size is greater than that value are considered unqualified.

[0096] In addition, refer to Figure 1 and Figure 5 The insect killer disclosed herein also includes a safety mechanism to prevent accidental activation of the triggering element 4. The safety mechanism includes an electromagnet locking pin 61 and a safety switch 62. The electromagnet locking pin 61 is fixedly installed inside the housing 1, and its core retracts when energized and extends under the action of a spring when de-energized. The triggering element 4 has a locking hole or groove corresponding to the end of the core of the electromagnet locking pin 61 as a locking part 411.

[0097] The safety switch 62 can be a slide switch, push button switch or inductive switch, and is located on the housing 1 in an easily accessible position and is electrically connected to the control unit 7.

[0098] This mosquito-killing gun lacks a manual loading mechanism, potentially diminishing the satisfying experience of firing a firearm. Therefore, reference... Figure 13 The safety switch 62 includes a sliding part 63, which is slidably disposed on the housing 1; when the sliding part 63 slides a preset distance, the safety switch 62 is activated. The safety switch 62 is configured to simulate the loading action of a traditional firearm, so that the safety switch 62 can be activated by sliding the sliding part 63 backward, thereby enhancing the shooting pleasure.

[0099] When the insect killer is powered on but not in firing preparation mode, the control unit 7 controls the electromagnet locking pin 61 to be in the de-energized extended state, with its iron core inserted into the locking part 411 of the firing element 4, physically blocking the backward sliding stroke of the firing element 4, preventing it from being pulled, thus achieving a safety lock. When the user needs to fire, the safety switch 62 must be activated first. After the safety switch 62 is triggered, it sends an unlocking signal to the control unit 7. In response to the unlocking signal, the control unit 7 supplies power to the electromagnet locking pin 61, causing its iron core to retract, thereby releasing the lock on the firing element 4. Only then can the user pull the firing element 4 to fire. To improve safety, the control unit 7 can be configured to start a timer after receiving the unlocking signal. If no firing command from the firing element 4 is detected within a preset time (e.g., 3 seconds), the power supply to the electromagnet locking pin 61 is automatically cut off, causing the iron core to extend again and relock the firing element 4. This avoids the risk of the user forgetting to fire and leaving the device in the unlocked state for an extended period. The preset time after the safety lock is unlocked is not limited to 3 seconds; it can be set to 1 second, 2 seconds, 5 seconds, etc., as needed. In another control logic, the control unit 7 is also configured to automatically control the electromagnet locking pin 61 to restore power (or de-energize) its iron core after the energy storage unit 2 re-enters the energy storage state and remains stable, thereby restoring the safety mechanism to the locked state and preparing for the next safe firing.

[0100] Optionally, the control unit 7 is configured to return to a state ready to accept the next firing command after a preset interval following the receipt of a firing command. The preset interval can be between 600ms and 1100ms, preferably 800ms. If the preset interval is too short, below 600ms, it may prevent the trigger 41 from being pressed too quickly, which could cause the projectile to not have enough time to enter the firing tube 8, resulting in a jam. If the preset interval is too long, greater than 1100ms, the interval between two consecutive firings will be too long, i.e., greater than 1100ms, affecting the efficiency of continuous firing.

[0101] Additionally, see Figure 2 The insect killer disclosed herein also includes a power module 10 for supplying power to various electrical components such as the drive source 31, control unit 7, and electromagnet. The power module 10 can be a battery pack (such as a rechargeable lithium battery or dry cell battery). A power switch 111 is provided on the housing 1 to control the power on and off of the entire device. Furthermore, to facilitate user monitoring of the power module 10's battery level, a power indicator light 112 is provided on the housing 1. Both the power switch 111 and the power indicator light 112 can be located on the rear cover 11. Multiple power indicator lights 112 can be provided, such as 3, 4, or 5. When 5 lights are provided, they represent the remaining battery level from top to bottom: 100%, 80%, 60%, 40%, and 20%.

[0102] The working process of the insect killer provided in this embodiment includes the following stages: Initial loading stage: The user turns on the power switch 111, and the control unit 7 is powered on. The control unit 7 controls the drive source 31 to start, and the drive source 31 drives the incomplete gear 322 to rotate through the self-locking component. The toothed part of the incomplete gear 322 meshes with the rack 321, pulling the piston to move backward and compressing the energy storage component 23.

[0103] When the piston moves to the preset energy storage position, the magnetic element 91 on the piston reaches directly below the Hall sensor 92, and the Hall sensor 92 generates a positioning signal. After receiving the positioning signal, the control unit 7 controls the drive source 31 to stop. Due to the self-locking characteristic of the self-locking assembly, the piston is reliably locked in the energy storage position, and the insect killer enters the ready-to-fire state.

[0104] Firing preparation phase: The user activates the safety switch 62, for example, by pressing the safety switch 62. After receiving the unlock signal, the control unit 7 controls the electromagnet locking pin 61 to be energized, the locking pin retracts, and the unlock trigger 41 is released. At the same time, the control unit 7 starts a timer.

[0105] Firing and synchronous feeding stage: The user pulls the trigger 41 within a preset time (e.g., 3 seconds). As the trigger 41 slides backward, on the one hand, the linkage component drives the feed rod 52 to slide downward, sending the projectile in the feed hole 521 into the firing tube 8; on the other hand, the trigger 41 touches and closes the micro switch 42, and the micro switch 42 issues a firing command.

[0106] After receiving the firing command from the micro switch 42, the control unit 7 controls the drive source 31 to rotate. After rotating by a small angle, the toothless part of the incomplete gear 322 rotates to a position opposite to the rack 321. At this time, the transmission assembly 32 exits the first state and enters the second state, and the power transmission between the piston and the drive source 31 is cut off.

[0107] Under the immense thrust of the energy storage component 23, the piston moves forward at high speed, compressing the air in the cylinder 21 to generate a high-pressure airflow. This high-pressure airflow enters the launch tube 8, propelling the projectile within it out at high speed, thus completing the firing.

[0108] Automatic reset phase: During projectile firing, the incomplete gear 322 continues to rotate. When the toothed part re-engages with the rack 321, it begins to pull the piston backward, recompressing the energy storage unit 23. When the piston moves back to the energy storage position, the magnetic element 91 triggers the Hall sensor 92 again, and the control unit 7 executes the shutdown of the drive source 31. The piston is locked in the energy storage position, and the insect killer automatically returns to the ready-to-fire state, preparing for the next shot.

[0109] After each shot, trigger 41 resets, and the firearm automatically returns to the powered state (i.e., loaded). To fire again, the user simply presses the safety switch 62 and pulls trigger 41. The entire process is automatic, requiring no user intervention, with an interval of only 600ms to 1100ms between consecutive shots, for example, 800 milliseconds. This convenient and quick operation effectively improves the efficiency of continuous firing.

[0110] If the user does not pull the trigger 41 within the preset time after activating the safety switch 62, the control unit 7 de-energizes the electromagnet locking pin 61, causing the pin to extend again and lock the trigger 41, keeping the insect killer in a safe, ready-to-fire state. If the user needs to fire again, the safety switch 62 must be reactivated.

[0111] It is understandable that the control unit 7, as the core logic processing and command center of the insect killer, mainly includes a microcontroller unit (MCU), an input signal conditioning circuit, an output drive circuit, and a stable power supply provided by a power conversion circuit.

[0112] The stable voltage (VCC) powers the entire control unit 7. The core of control unit 7 is a microcontroller (a general-purpose MCU with corresponding I / O ports and timers can be selected), whose VCC pin and GND pin are connected to the +5V power supply and ground, respectively.

[0113] Input channel: The output of Hall sensor 92 is connected to a general-purpose input / output (GPIO) pin with interrupt functionality on the MCU (e.g., PIN_HALL). When the magnetic element 91 triggers Hall sensor 92, this pin is pulled high or low, and the MCU can detect this level change.

[0114] One end of the microswitch 42 is grounded, and the other end is connected to a GPIO pin of the MCU (denoted as PIN_TRIGGER). When the trigger 41 closes the microswitch 42, this pin is pulled low, and the MCU can detect the low-level trigger signal.

[0115] One end of the safety switch 62 is grounded, and the other end is connected to a GPIO pin of the MCU (denoted as PIN_SAFETY). When the user activates the safety switch 62, this pin is pulled low.

[0116] The signal line of power switch 111 is also connected to a GPIO pin of the MCU (denoted as PIN_PWR) to indicate the main power supply status (optional, or initialized by detecting VCC power-on).

[0117] Output channels: One of the MCU's GPIO pins (denoted as PIN_DRV) is connected to the driver source 31 through a motor drive circuit (such as an H-bridge or MOSFET switch). When this pin outputs a high level, the driver source 31 starts; when it outputs a low level, the driver source 31 stops.

[0118] One of the MCU's GPIO pins (denoted as PIN_SOL) is connected to the electromagnet locking pin 61 via a switching transistor (such as a bipolar transistor or MOSFET). When this pin outputs a high level, the switching transistor is turned on, and the electromagnet locking pin 61 is energized and retracted; when the output is low, the electromagnet locking pin 61 is de-energized and extended.

[0119] The MCU's internal program memory stores the control logic code, and its internal timer / counter is used to achieve precise timing of preset times (such as 3 seconds).

[0120] The above are all preferred embodiments of this disclosure and are not intended to limit the scope of protection of this disclosure. Therefore, all equivalent changes made to the structure, shape and principle of this disclosure should be included within the scope of protection of this disclosure.
