Description

Technical Field

[0001] This invention relates to the technical field of drug delivery, and in particular to a long-acting, sustained-release drug delivery device for vector-borne disease control. Background Technology

[0002] Vector-borne disease control refers to the control of harmful organisms (mainly mosquitoes, flies, rats, and cockroaches, the "four pests") that transmit diseases (such as plague, malaria, dengue fever, and Japanese encephalitis) through environmental management, physical control, chemical control, and biological control. Generally, long-term control is achieved by applying gel-like long-acting slow-release agents (hereinafter referred to as agents). Currently, most of these agents are applied through methods such as the cockroach bait dispenser disclosed in patent CN208159913U and the multifunctional combined cockroach-killing device disclosed in utility model patent CN203087348U.

[0003] However, during use, it was found that in order to reduce the impact of the pesticide on the surrounding environment and people, and at the same time improve the contact effect between the disease vector and the pesticide, the pesticide needs to be placed in a relatively narrow gap or above the ceiling. However, the existing pesticide delivery device has a relatively simple structure, which is inconvenient for delivery in narrow places, resulting in poor practicality. Therefore, there is an urgent need for a long-acting slow-release pesticide delivery device for disease vector control to improve the above problems. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a long-acting, slow-release pesticide dispensing device for vector control. The device involves discharging the pesticide into a conveying mechanism, adjusting the pesticide's placement position through a guiding mechanism in conjunction with a supporting and bending mechanism, and simultaneously using a camera to assist staff in observing the pesticide's placement position. The conveying mechanism then passes the pesticide through the supporting mechanism to the designated placement position, thereby improving the device's practicality.

[0005] The present invention provides a long-acting sustained-release agent dispensing device for vector control, comprising a conveying mechanism; and further comprising an angle adjustment mechanism and a camera mechanism, wherein the angle adjustment mechanism is mounted on the conveying mechanism and the camera mechanism is mounted on the angle adjustment mechanism; The angle adjustment mechanism includes a guiding mechanism, a supporting mechanism, and a bending mechanism. The guiding mechanism is mounted on the conveying mechanism, and the supporting mechanism and the bending mechanism are both mounted on the guiding mechanism. The agent is fed into the conveying mechanism, and the placement position of the agent is adjusted by the guiding mechanism in conjunction with the supporting and bending mechanisms. At the same time, the camera assists the staff in observing the placement position of the agent. Then, the conveying mechanism runs to make the agent pass through the supporting mechanism and be placed at the placement position, thereby improving the practicality of the equipment.

[0006] Preferably, the conveying mechanism includes a storage cylinder, a shoulder strap, a piston, a replenishing valve, an electric cylinder, and a discharging valve. The shoulder strap is fixedly installed on the storage cylinder, the piston is slidably installed in the storage cylinder, the replenishing valve is installed on the piston, the electric cylinder is fixedly installed on the storage cylinder, and one end of the electric cylinder is connected to the piston. The discharging valve is installed at the bottom of the storage cylinder. By extending the electric cylinder, the piston is moved to the bottom of the storage cylinder, opening the replenishing valve and discharging the medicine into the storage cylinder. As the medicine continues to be discharged into the storage cylinder, the electric cylinder continuously contracts, adjusting the height of the piston. After the electric cylinder contracts to its limit, the replenishing valve is closed. When discharging medicine, the discharging valve is connected to the support mechanism. By extending the electric cylinder, the piston moves downward to squeeze the medicine in the storage cylinder, causing the medicine to pass through the discharging valve and the support mechanism in sequence before being discharged.

[0007] Preferably, the guiding mechanism includes a guide tube, a tubular handle, a support frame, and a braking mechanism. The tubular handle is fixedly installed at one end of the guide tube, the support frame is hinged to the other end of the guide tube, and the braking mechanism is installed on the support frame. By moving the support frame, the support mechanism is adjusted to bend, thus making a preliminary adjustment to the direction of drug delivery. Then, the braking mechanism locks the support frame to maintain its angle.

[0008] Preferably, the braking mechanism includes a locking bolt and a ball spring clamping pin. The other end of the guide tube is provided with several semi-circular grooves. The locking bolt is threaded onto the support frame, and the ball spring clamping pin is fixedly installed on the support frame. When the support frame is turned, the ball spring clamping pin rolls in several semi-circular grooves on the guide tube, increasing the damping. After the support frame is adjusted, the ball spring clamping pin is locked in a set of semi-circular grooves, which initially limits the position of the support frame. Then, the operator tightens the locking bolt, so that one end of the locking bolt squeezes the guide tube and locks the support frame.

[0009] Preferably, the movement trajectory of the ball spring clamping pin corresponds to several semi-circular grooves on the guide tube.

[0010] Preferably, the support mechanism includes a fixed frame, a winding shaft, a universal serpentine tube, two sets of gears, a dual-output motor, a discharging pipe, a connecting pipe, and a second connecting pipe. The fixed frame is fixedly mounted on the tubular handle, the winding shaft is rotatably mounted on the fixed frame, and a stator is provided on the fixed frame. A rotor is provided on the winding shaft. The universal serpentine tube is wound onto the winding shaft, and its other end passes sequentially through the tubular handle, the guide pipe, and the support frame. Both sets of gears are rotatably mounted in the support frame, and both sets of gears are meshed with the universal serpentine tube. The dual-output motor is fixedly mounted on the support frame, and the two output shafts of the dual-output motor are respectively connected to one end of the two sets of gears. The discharging pipe is mounted on... Mounted on the bending mechanism, one end of connecting pipe two is connected to the discharge valve, and one end of connecting pipe one is rotatably connected to connecting pipe two. The other end of connecting pipe one passes through the winding shaft, the universal serpentine tube, and the bending mechanism in sequence, and then connects to the discharge pipe. Through the operation of the stator, the rotor drives the winding shaft to rotate. At the same time, the dual-output motor operates, causing the two sets of gears one to mesh with the universal serpentine tube, and then conveying the universal serpentine tube to the outside of the support frame. The length of the universal serpentine tube outside the support frame is adjusted. Through the operation of the conveying mechanism, the medicine passes through connecting pipe two and connecting pipe one in sequence, and then is discharged through the discharge pipe. After the medicine is added, the universal serpentine tube is retracted into the discharge pipe by the reverse operation of the stator and the dual-output motor.

[0011] Preferably, the surface of the universal serpentine tube is wrapped with a square-structured rubber layer, and several gear teeth are provided at the top and bottom of the rubber layer. Two sets of gears respectively mesh with several gear teeth at the top and bottom of the rubber layer, thereby improving the convenience of conveying the universal serpentine tube.

[0012] Preferably, the bending mechanism includes a rotary connecting pipe, a bellows, a gear ring, a drive motor, a second gear, and a drive mechanism. The rotary connecting pipe is rotatably mounted on the universal serpentine pipe, the bellows is fixedly mounted on the rotary connecting pipe, the gear ring is fitted onto the rotary connecting pipe, the drive motor is fixedly mounted on the universal serpentine pipe, the second gear is mounted on the output shaft of the drive motor, and the second gear and the gear ring are meshed. The drive mechanism provides power to the bellows. By operating the drive mechanism, the bellows is bent. Then, the drive motor is turned on, and through the meshing transmission between the second gear and the gear ring, the bellows is driven to rotate, thereby adjusting the position and angle of the drug discharge pipe.

[0013] Preferably, the driving mechanism includes a long strip-shaped airbag, a pressure regulating cylinder, a bend, a connecting pipe three, a piston two, and an electric cylinder two. The long strip-shaped airbag is installed in the side wall of the bellows. The pressure regulating cylinder is fixedly installed on the fixed frame. One end of the bend is installed on the pressure regulating cylinder. One end of the connecting pipe three is connected to the long strip-shaped airbag, and the other end of the connecting pipe three is rotatably connected to the other end of the bend. The piston two is slidably installed in the pressure regulating cylinder. The electric cylinder two is fixedly installed on the pressure regulating cylinder, and one end of the electric cylinder two is connected to the piston two. When the electric cylinder two extends, the piston two slides in the pressure regulating cylinder, causing the air in the pressure regulating cylinder to flow sequentially through the bend and the connecting pipe three into the long strip-shaped airbag, which then inflates the long strip-shaped airbag, keeping the bellows straight. When the electric cylinder two contracts, the air in the long strip-shaped airbag is sucked out, causing the long strip-shaped airbag to contract, which in turn causes the bellows to bend.

[0014] Preferably, the camera mechanism includes a supplementary light, a miniature camera, and a controller. Both the supplementary light and the miniature camera are installed on the drug delivery pipe, and both are wirelessly connected to the controller. The supplementary light provides illumination for the miniature camera, the miniature camera observes the drug delivery location, the controller enables the operator to control the electrical components of the equipment, and the controller displays the images captured by the miniature camera.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up a multi-level angle adjustment structure consisting of a guiding mechanism, a supporting mechanism, and a bending mechanism, the device can flexibly bend and penetrate into narrow gaps or extend to hard-to-reach locations such as ceilings, solving the problem that traditional devices cannot effectively deliver drugs in complex environments. 2. By installing a camera at the end of the discharge pipe, staff can observe hidden dosing points that are not directly visible to the naked eye in real time, and display the images through the controller, thereby ensuring that the pesticides can be accurately delivered to the target location. 3. The conveying mechanism adopts a backpack-style storage tube design, which is convenient for staff to carry; at the same time, through the cooperation of the winding shaft and dual output motors, the extension and retraction of the universal serpentine tube can be electrically controlled, which greatly simplifies the operation process and improves the efficiency of drug delivery in complex environments.

The movement trajectory of the ball spring clamping pin 11 corresponds to several semi-circular grooves on the guide tube 7; The support mechanism includes a fixed frame 12, a winding shaft 13, a universal serpentine tube 16, two sets of gears 17, a dual-output motor 18, a discharging pipe 19, a connecting pipe 20, and a connecting pipe 21. The fixed frame 12 is fixedly mounted on the tubular handle 8, the winding shaft 13 is rotatably mounted on the fixed frame 12, and a stator 14 is provided on the fixed frame 12. A rotor 15 is provided on the winding shaft 13, and the universal serpentine tube 16 is wound onto the winding shaft 13. The other end of the universal serpentine tube 16 passes sequentially through the tubular handle 8, the guide pipe 7, and the support frame 9. The two sets of gears 17... All are rotatably mounted in the support frame 9, and both sets of gears 17 are meshed with the universal serpentine tube 16. The dual output motor 18 is fixedly mounted on the support frame 9, and the two output shafts of the dual output motor 18 are respectively connected to one end of the two sets of gears 17. The medicine discharge tube 19 is mounted on the bending mechanism. One end of the connecting tube 21 is connected to the medicine discharge valve 6. One end of the connecting tube 20 is rotatably connected to the connecting tube 21. The other end of the connecting tube 20 passes through the winding shaft 13, the universal serpentine tube 16 and the bending mechanism in sequence, and then connects to the medicine discharge tube 19. The surface of the universal serpentine tube 16 is covered with a square-structured rubber layer, and several gear teeth are provided at the top and bottom of the rubber layer. Two sets of gears 17 respectively mesh with several gear teeth at the top and bottom of the rubber layer. The bending mechanism includes a rotary connecting pipe 22, a bellows pipe 23, a gear ring 24, a drive motor 25, a second gear 26, and a drive mechanism. The rotary connecting pipe 22 is rotatably mounted on the universal serpentine pipe 16, the bellows pipe 23 is fixedly mounted on the rotary connecting pipe 22, the gear ring 24 is fitted onto the rotary connecting pipe 22, the drive motor 25 is fixedly mounted on the universal serpentine pipe 16, the second gear 26 is mounted on the output shaft of the drive motor 25, and the second gear 26 and the gear ring 24 are meshed. The drive mechanism provides power to the bellows pipe 23. The drive mechanism includes a long strip-shaped airbag 27, a pressure regulating cylinder 28, a bend 29, a connecting pipe 30, a piston 31, and an electric cylinder 32. The long strip-shaped airbag 27 is installed in the side wall of the bellows 23. The pressure regulating cylinder 28 is fixedly installed on the fixing frame 12. One end of the bend 29 is installed on the pressure regulating cylinder 28. One end of the connecting pipe 30 is connected to the long strip-shaped airbag 27, and the other end of the connecting pipe 30 is rotatably connected to the other end of the bend 29. The piston 31 is slidably installed in the pressure regulating cylinder 28. The electric cylinder 32 is fixedly installed on the pressure regulating cylinder 28, and one end of the electric cylinder 32 is connected to the piston 31. By extending the electric cylinder 5, the piston 3 is moved to the bottom of the storage cylinder 1, opening the replenishment valve 4 and discharging the medicine into the storage cylinder 1. As the medicine continues to be discharged into the storage cylinder 1, the electric cylinder 5 continuously contracts, adjusting the height of the piston 3. After the electric cylinder 5 contracts to its limit, the replenishment valve 4 is closed. When discharging the medicine, the operator holds the tubular handle 8 and manipulates the support frame 9, thereby adjusting the universal serpentine tube 16 to bend and initially adjust the direction of medicine dispensing. Then, the operator tightens the locking bolt 10, causing one end of the locking bolt 10 to press against the guide tube 7, locking the support frame 9. Then, the stator 14 operates, causing the rotor 15 to drive the winding shaft 13 to rotate. Simultaneously, the dual-output motor 18 operates, causing two sets of gears 17 to mesh with the universal serpentine tube 16, thus conveying the universal serpentine tube 16 out of the support frame 9. The length of the universal serpentine tube 16 outside the support frame 9 is adjusted, and then... Cylinder 22 contracts, drawing air out of the elongated airbag 27, causing it to contract. This causes the bellows 23 to bend, readjusting the direction of drug delivery. Then, the discharge pipe 19 is inserted into the narrow position, aligning it with the delivery location. Cylinder 15 extends, causing piston 13 to move downwards, compressing the drug in storage cylinder 1. The drug passes through connecting pipe 21 and connecting pipe 10, and is then discharged through discharge pipe 19. After the drug is delivered, the stator 14 and the dual-output motor 18 reverse their rotation, retracting the universal serpentine pipe 16 into discharge pipe 19. Simultaneously, Cylinder 22 extends, causing piston 21 to slide in the pressure regulating cylinder 28. This allows air in the pressure regulating cylinder 28 to flow through the bend pipe 29 and connecting pipe 30 into the elongated airbag 27, causing it to expand and restoring the bellows 23 to its straight state, thus improving the equipment's practicality.

[0020] Example 2: A long-acting sustained-release agent dispensing device for vector control, which, based on Example 1, further includes: The camera mechanism includes a fill light 33, a miniature camera 34 and a controller 35. The fill light 33 and the miniature camera 34 are both installed on the drug delivery tube 19, and the fill light 33 and the miniature camera 34 are both wirelessly connected to the controller 35. By extending the electric cylinder 5, piston 3 is moved to the bottom of storage cylinder 1, opening the replenishment valve 4 and discharging the medicine into storage cylinder 1. As the medicine continues to be discharged into storage cylinder 1, electric cylinder 5 continuously retracts, adjusting the height of piston 3. After electric cylinder 5 retracts to its limit, replenishment valve 4 is closed. When discharging the medicine, the operator holds the tubular handle 8 and manipulates the support frame 9, thereby adjusting the universal serpentine tube 16 to bend and initially adjust the direction of medicine dispensing. Then, the operator twists... Tighten the locking bolt 10 so that one end of the locking bolt 10 presses against the guide tube 7, locking the support frame 9. Then, the stator 14 runs, causing the rotor 15 to drive the winding shaft 13 to rotate. At the same time, the dual-output motor 18 runs, causing the two sets of gears 17 to mesh with the universal serpentine tube 16, which then conveys the universal serpentine tube 16 out of the support frame 9. Adjust the length of the universal serpentine tube 16 outside the support frame 9, and then retract the electric cylinder 32 to suck out the air from the long strip-shaped airbag 27, causing the long strip-shaped airbag 27 to contract, and then the wave... The tube 23 is bent to readjust the direction of drug delivery. Then, the discharge tube 19 is inserted into the narrow position. Simultaneously, the drug delivery position is observed through the miniature camera 34. The controller 35 enables the operator to control the electrical components of the equipment and displays the image captured by the miniature camera 34. The discharge tube 19 is aligned with the delivery position. The electric cylinder 5 extends, causing the piston 3 to move downwards and squeeze the drug in the storage cylinder 1, forcing the drug to pass sequentially through the connecting tube. The tube 21 and connecting pipe 20 are then discharged through the discharge pipe 19. After the medicine is added, the universal serpentine tube 16 is retracted into the discharge pipe 19 by the reverse operation of the stator 14 and the dual-output motor 18. At the same time, the electric cylinder 22 extends and the piston 21 slides in the pressure regulating cylinder 28, so that the air in the pressure regulating cylinder 28 flows through the bend pipe 29 and connecting pipe 30 into the long strip air bag 27, which then inflates the long strip air bag 27, restoring the bellows 23 to a straight state, thereby improving the practicality of the equipment.

[0021] The main functions achieved by this invention are: 1. By setting up a multi-level angle adjustment structure consisting of a guiding mechanism, a supporting mechanism, and a bending mechanism, the device can flexibly bend and penetrate into narrow gaps or extend to hard-to-reach locations such as ceilings, solving the problem that traditional devices cannot effectively deliver drugs in complex environments. 2. By installing a camera at the end of the discharge pipe, staff can observe hidden dosing points that are not directly visible to the naked eye in real time, and display the images through the controller, thereby ensuring that the pesticides can be accurately delivered to the target location. 3. The conveying mechanism adopts a backpack-style storage tube design, which is convenient for staff to carry; at the same time, through the cooperation of the winding shaft and dual output motors, the extension and retraction of the universal serpentine tube can be electrically controlled, which greatly simplifies the operation process and improves the efficiency of drug delivery in complex environments.

[0022] To avoid redundancy and to clearly demonstrate the internal transmission relationship of the bending mechanism, this application does not add additional protective covers to the transmission components such as motors, gears, and gear rings. It should be noted that in actual production applications, in order to prevent foreign objects from entering or causing mechanical damage, it is a conventional technical means in this field to put protective covers on the outside of these transmission components (especially the meshing point between the motor output end and the gear ring).

Its installation, connection, or setting methods are all common mechanical methods, and any method that achieves the beneficial effect can be implemented.

Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual, without requiring any creative effort from those skilled in the art.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
