This device is suitable for various insecticide spray cans without requiring modification or customization of the can itself, making it widely applicable.

[0023] In a further preferred embodiment of this utility model, the pressing mechanism includes a sleeve 9, a push rod 10, a sliding groove 11, a connecting block 12, and a driving mechanism. The sleeve 9 is fixedly installed on the top inner wall of the mounting cover 8. The push rod 10 is slidably installed inside the sleeve 9. The sliding groove 11 is formed on the side wall of the sleeve 9. The connecting block 12 is fixedly installed on the push rod 10. The connecting block 12 extends through the sliding groove 11 to the outside of the sleeve 9. The driving mechanism for driving the push rod 10 to rise and fall is disposed inside the mounting cover 8.

[0024] In this embodiment, the sleeve 9 serves as the track and support for the sliding of the push rod 10. The push rod 10 transmits driving force by sliding up and down, thereby pushing the upright 4 and the pressing block 5. The groove 11 allows the connecting block 12 to pass through and extend outside the sleeve 9, for connecting and driving the push rod 10 to rise and fall. After the connecting block 12 passes through the groove 11, the user can raise and lower the push rod 10 by operating the connecting block 12. The drive mechanism provides the driving force required to raise and lower the push rod 10. By operating the connecting block 12, the user can drive the push rod 10 to slide up and down within the sleeve 9. The sliding of the push rod 10 pushes the upright 4 downward, thereby pressing the button on the insecticide spray can 2 via the pressing block 5, releasing the insecticide. After release, the restoring force of the spring 7 pulls the upright 4, the pressing block 5, and the push rod 10 back to their original positions, ready for the next operation. By introducing the drive mechanism and the connecting block 12, the user can operate the insecticide spraying device more easily without having to directly and forcefully press the button on the spray can. The drive mechanism can provide more precise and stable driving force, making the release of pesticides more uniform and controllable.

[0025] In a further preferred embodiment of the present invention, the driving mechanism includes a drive motor 13, a turntable 14, an eccentric shaft 15, and a traction rope 16. The drive motor 13 is fixedly installed inside the mounting cover 8, the turntable 14 is fixedly installed on the output shaft of the drive motor 13, the eccentric shaft 15 is fixedly installed on the turntable 14, one end of the traction rope 16 is fixedly installed on the connecting block 12, and the other end is sleeved on the eccentric shaft 15.

[0026] In this embodiment, the drive motor 13 serves as the core component of the drive mechanism, providing the power source. The turntable 14 rotates with the drive motor. The eccentric shaft 15 rotates in a circular motion with the turntable, but its axis does not coincide with the turntable's axis, thus exhibiting eccentric characteristics. The traction rope 16 pulls the connecting block 12 and the push rod 10 up and down through the circular motion of the eccentric shaft. When the drive motor 13 starts, the turntable 14 begins to rotate, thereby driving the eccentric shaft 15 to rotate. Since the axis of the eccentric shaft 15 does not coincide with the turntable's axis, one end of the traction rope 16, which is sleeved on the eccentric shaft 15, will reciprocate radially with its circular motion. This radial movement is transmitted to the connecting block 12 through the traction rope 16, thereby causing the push rod 10 to slide up and down within the sleeve 9. The sliding of the push rod 10 pushes the upright 4 downward, and the press button on the insecticide spray can 2 is pressed by the press block 5 to release the insecticide. When the drive motor 13 reverses or stops, the circular motion of the eccentric shaft 15 changes direction or stops, thereby pulling the push rod 10 back to its original position or holding it in a certain position via the traction rope 16 and connecting block 12. By introducing components such as the drive motor 13 and turntable 14, the insecticide spraying device is automated, allowing users to release the insecticide without manually operating the connecting block 12. This automation and precise control make the user experience easier and more convenient, increasing user satisfaction and loyalty.

[0027] In a further preferred embodiment of the present invention, a rubber pad 17 is fixedly installed inside the protective cover 1, and the rubber pad 17 comes into contact with the insecticide spray can 2 and deforms.

[0028] In this embodiment, when the insecticide spray can 2 is placed inside the protective cover 1, the rubber pad 17 deforms against the outer surface of the spray can due to its elasticity and softness, ensuring a tight fit between the two. This tight fit not only helps to secure the insecticide spray can 2, preventing it from shaking or moving within the device, but also reduces the impact of external shocks on the spray can to a certain extent, protecting it from damage. The elasticity and softness of the rubber pad 17 can absorb external impacts, protecting the insecticide spray can 2 from damage and extending its service life. The improved stability and protection give users greater peace of mind during use, increasing user satisfaction and loyalty.

[0029] In a further preferred embodiment of this utility model, the bottom of the protective cover 1 is for replacing the open-mouth insecticide spray can 2. The bottom of the protective cover 1 is threaded with a cap 18, and a screw 19 is rotatably mounted on the cap 18. A mounting bracket 20 is threaded on the screw 19. An adjusting block 21 that contacts the bottom of the insecticide spray can 2 is fixedly mounted on the top of the mounting bracket 20. A guide rod 22 is fixedly mounted on the cap 18, and the guide rod 22 slides through the mounting bracket 20.

[0030] In this embodiment, when it is necessary to replace the insecticide spray can 2, the user can first unscrew the cap 18 to expose the opening of the protective cover 1, remove the old insecticide spray can 2, and then insert the new insecticide spray can 2, tightening the cap 18. Then, the height of the mounting bracket 20 is adjusted by rotating the screw 19, so that the adjusting block 21 contacts and fits tightly with the bottom of the newly replaced insecticide spray can 2, firmly fixing the spray can inside the protective cover 1, completing the replacement process. Throughout the process, the guide rod 22 provides stable guidance and support for the mounting bracket 20, ensuring a smooth replacement process. By introducing components such as the cap 18, screw 19, mounting bracket 20, and adjusting block 21, the rapid replacement of the insecticide spray can 2 is achieved without disassembling the entire device or complex operating procedures. The tight fit between the adjusting block 21 and the bottom of the insecticide spray can 2, as well as the adjusting action of the screw 19 and mounting bracket 20, ensures the stable fixation of the spray can within the device, preventing shaking or movement. The guide rod 22 provides stable guidance and support for the mounting bracket 20, ensuring smooth movement and positioning of the mounting bracket during replacement. The improved ease of replacement and stability make the process easier and more convenient for users, increasing user satisfaction and loyalty.

[0031] In a further preferred embodiment of this utility model, limit blocks are fixedly installed on the top of both the screw 19 and the guide rod 22.

[0032] In this embodiment, the limiting block plays a crucial role when the user rotates the screw 19 to adjust the height of the mounting bracket 20. As the mounting bracket 20 rises, it contacts the limiting block at the top of the screw 19 and guide rod 22, thus preventing it from rising further. This confines the mounting bracket 20 within a safe range, avoiding the risk of it detaching from the screw 19 and guide rod 22 due to excessive rising. The presence of the limiting block ensures that the mounting bracket 20 will not detach from the screw 19 and guide rod 22 during height adjustment, thereby avoiding safety hazards caused by loosening or damage to the device. The design of the limiting block allows the user to more easily perceive when to stop rotating the screw 19 while adjusting the height of the mounting bracket 20, thus simplifying the operation process. Because the limiting block prevents the mounting bracket 20 from excessive rising and falling off, it also reduces the risk of device damage due to improper operation, thereby extending the device's service life.

[0033] In a further preferred embodiment of the present invention, a storage groove 23 is provided at the bottom of the cover 18, and a knob 24 is fixedly installed at the bottom of one end of the screw 19 extending into the storage groove 23, and the knob 24 is embedded in the storage groove 23.

[0034] In this embodiment, the storage slot 23 is used to accommodate and conceal the knob 24, making the device look neater and more aesthetically pleasing. The user can rotate the knob 24 to rotate the screw 19, thereby adjusting the height of the mounting bracket 20. The knob 24 is embedded in the storage slot 23, facilitating operation and maintaining the device's neatness. When it is necessary to replace the insecticide spray can 2 or adjust its height, the user can hold the knob 24 and rotate it, thereby rotating the screw 19. As the screw 19 rotates, the mounting bracket 20 moves up and down along the screw 19 and guide rod 22 until the adjusting block 21 is tightly fitted against the bottom of the insecticide spray can 2. At this point, the user can stop rotating the knob 24, completing the adjustment process. Because the knob 24 is embedded in the storage slot 23, it does not protrude from the surface of the cap 18, thus maintaining the device's neatness and aesthetics. The design of the knob 24 being embedded in the storage slot 23 makes the device look neater and more aesthetically pleasing, avoiding the visual clutter caused by a protruding knob. The design of the knob 24 being embedded in the storage slot 23 also reduces the risk of collisions or scratches caused by the knob protruding, thereby improving the safety of the device.

[0035] In summary, compared with related technologies, this improved device structure avoids the problems of insufficient hand strength for single-handed operation or easy slippage, reducing the danger of using insecticides. Users can release insecticide with simple operation, without the need for strenuous pressing of the spray can's button. By introducing components such as a drive motor, turntable, eccentric shaft, and traction rope, the insecticide spraying device achieves automated operation; users can release insecticide without manually operating the connecting block, increasing the degree of automation. This device is suitable for various insecticide spray cans without requiring modification or customization of the cans themselves, exhibiting wide applicability. The introduction of components such as a cap, screw, mounting bracket, and adjusting block enables quick replacement of insecticide spray cans without disassembling the entire device or complex operating procedures, improving ease of replacement. The tight fit between the adjusting block and the bottom of the insecticide spray can, along with the adjustment function of the screw and mounting bracket, ensures the stable fixation of the spray can within the device, preventing shaking or movement and improving safety. The knob's embedded design in the storage slot makes the device more neat and aesthetically pleasing.
