[0022] Please see Figures 1-5 A protective structure for an outdoor unit of a blower includes an outdoor unit body 1, an air inlet of the outdoor unit body 1 connected to a ventilation shell 2, a dustproof net 5 provided inside the ventilation shell 2, and a dust shaking mechanism 3 and a dust blowing mechanism 4 provided inside the ventilation shell 2.

[0023] The combination of the dust-shaking mechanism 3 and the dust-blowing mechanism 4 can automatically remove dust from the dustproof net 5, avoid the increase in air intake resistance caused by dust accumulation, and ensure the air intake volume and operating efficiency of the blower's outdoor unit 1. By integrating the dust-shaking mechanism 3 and the dust-blowing mechanism 4 inside the ventilation shell 2, the dust removal function is automated and efficient. This design integrates dust prevention, dust shaking and dust blowing functions into one structure, avoiding the limitations of single-function design.

[0024] The dust removal mechanism 3 includes two transmission rods 301. The transmission rods 301 are rotatably connected to the bottom of the inner wall of the ventilation shell 2. The top of the transmission rods 301 passes through the ventilation shell 2. The transmission rods 301 are rotatably connected to the surface of the ventilation shell 2 at the point of penetration. The surface of the transmission rods 301 is provided with reciprocating threads. Two cams 302 are fixed on the surface of the transmission rods 301. The surface of the cams 302 is slidably connected to the surface of the dustproof net 5. The dustproof net 5 is slidably connected to the inner wall of the ventilation shell 2. A movable sleeve 306 is threadedly connected to the surface of the transmission rods 301. Two side blocks 303 are fixed on both sides of the inner wall of the ventilation shell 2. A tension spring 304 is fixed on the surface of the side blocks 303. A connecting block 305 is fixed to one end of the tension spring 304. The connecting block 305 is detachably connected to the dustproof net 5. A drive structure is provided at the top of the ventilation shell 2. Limit blocks 307 are fixed on both the upper and lower sides of the reciprocating thread of the transmission rods 301.

[0025] The transmission rod 301 rotates via a top drive structure. The surface of the transmission rod 301 is provided with reciprocating threads. This thread design allows the movable sleeve 306, which is threadedly connected to it, to move up and down along its axial direction when the transmission rod 301 rotates, thereby driving the components in the dust blowing mechanism 4 to move. The limiting block 307 is used to limit the range of movement of the movable sleeve 306, preventing it from dislodging or moving excessively on the thread. When the transmission rod 301 rotates, the eccentric structure of the cam 302 periodically pushes the dustproof net 5, while the tension spring 304 acts as a buffer and reset mechanism, achieving the vibration effect of the dustproof net 5. Through the efficient vibration of the dustproof net 5, the dust accumulated on its surface is effectively removed, preventing reduced airflow and decreased equipment performance caused by dust accumulation. Furthermore, the dustproof net 5 and the connecting block 305 are detachably connected, facilitating the cleaning and replacement of the dustproof net 5 and improving the maintenance convenience of the equipment.

[0026] Furthermore, the top drive structure of the ventilation housing 2 includes a support frame 308, which is fixed to the top of the ventilation housing 2. A motor 309 is fixed to the top of the support frame 308. The output shaft of the motor 309 passes through the support frame 308 and is fixedly connected to the top of a transmission rod 301 on one side. A transmission wheel 310 is fixed to the top of the transmission rod 301. The transmission wheels 310 on the left and right sides are connected by belt drive.

[0027] The output shaft of motor 309 is connected to the transmission rods 301 on both sides through transmission wheel 310 and belt, so that the transmission rods 301 on both sides rotate synchronously, thereby driving the dust shaking mechanism 3. Furthermore, the use of motor 309 for driving results in a simple structure, stable operation, and improved equipment maintenance efficiency.

[0028] Furthermore, the dust blowing mechanism 4 includes an air pump 401 and an air outlet shell 402. The air outlet shell 402 is fixedly connected to the surface of the movable sleeve 306. The air pump 401 is fixed to the top of the ventilation shell 2. A rigid pipe 403 is connected to the surface of the air pump 401. One end of the rigid pipe 403 passes through the ventilation shell 2 and is connected to a telescopic hose 404. One end of the telescopic hose 404 is connected to the surface of the air outlet shell 402. An exhaust port is provided on the front surface of the air outlet shell 402.

[0029] Air pump 401 delivers compressed air to air outlet shell 402 through rigid pipe 403 and telescopic hose 404. Air outlet shell 402 blows airflow toward dust filter 5 through exhaust port, further blowing loose dust away from dust filter 5. Combined with dust shaking mechanism 3, the airflow can more thoroughly remove dust from dust filter 5, improve dust removal efficiency, reduce dust pollution inside the equipment, and extend the service life of the equipment.

[0030] Furthermore, an air guide shell 405 is fixed to the front surface of the air outlet shell 402. An air outlet is provided on the front side of the air guide shell 405. The air guide shell 405 has a trapezoidal structure design.

[0031] The air guide shell 405 has a trapezoidal structure design. Its air outlet guides the airflow blown out by the air outlet shell 402 to the surface of the dustproof net 5, optimizes the airflow direction, makes the airflow more concentrated, improves the dust blowing effect, reduces the waste of airflow, and improves the overall efficiency of the dust removal system.

[0032] Furthermore, guide frames 311 are fixed on both the left and right sides of the inner wall of the ventilation shell 2. A sliding sleeve is slidably connected to the surface of the guide frame 311, and the surface of the sliding sleeve is fixedly connected to the surface of the air outlet shell 402.

[0033] The guide frame 311 is connected to the air outlet shell 402 through the sliding sleeve, providing guidance for the movement of the air outlet shell 402, ensuring that the air outlet shell 402 moves smoothly under the drive of the movable sleeve 306, avoiding the positional deviation of the air outlet shell 402, and ensuring the consistency of the dust blowing effect.

[0034] Furthermore, threaded holes are provided on the surfaces of both the connecting block 305 and the dustproof net 5, and the connecting block 305 and the dustproof net 5 can be detachably connected by bolts through the threaded holes;

[0035] The connecting block 305 and the dustproof net 5 are detachably connected through threaded holes and bolts, which facilitates the installation and replacement of the dustproof net 5. The bolt connection method is simple in structure, easy to maintain, and reduces maintenance costs and time.

[0036] Furthermore, guide rails 8 are fixed on both the left and right sides of the inner wall of the ventilation shell 2, and the dustproof net 5 is slidably connected to the surface of the guide rails 8.

[0037] The dustproof net 5 is slidably connected to the guide rail 8 and moves back and forth along the guide rail 8 during the dust removal process, ensuring that the vibration of the dustproof net 5 is more stable, avoiding the position displacement or damage of the dustproof net 5 due to vibration, and extending the service life of the dustproof net 5.

[0038] Furthermore, a rainproof frame 6 is fixed to the top of the ventilation shell 2, and four waterproof and breathable membranes 7 are fixed to the surface of the rainproof frame 6;

[0039] The combination of the rainproof frame 6 and the waterproof and breathable membrane 7 effectively prevents rainwater from corroding the equipment, while not affecting the air intake function, thus improving the reliability of the equipment under harsh weather conditions.

[0040] Working Principle: When the outdoor unit 1 of the blower is running, external air first enters the system through the ventilation shell 2. The dustproof net 5 installed inside the ventilation shell 2 performs preliminary filtration of the incoming air, intercepting dust, impurities, and other particulate matter to prevent them from entering the interior of the outdoor unit 1, thereby protecting the equipment from contamination. During the filtration process, dust gradually accumulates on the dustproof net 5, affecting its permeability. When cleaning is required, the transmission rod 301 is rotated by the cooperation of the motor 309 and the transmission wheel 310. During the rotation, the reciprocating thread drives the movable sleeve 306 to move up and down along the transmission rod 301. At the same time, the eccentric design of the cam 302, combined with the reset effect of the tension spring 304, periodically pushes the dustproof net 5, causing it to... The vibration causes the dust on the dustproof net 5 to loosen and fall off. To further remove the dust from the dustproof net 5, the air pump 401 delivers compressed air to the air outlet shell 402 through the rigid pipe 403 and the telescopic hose 404. The air outlet shell 402 has an exhaust port on the front side. The airflow is concentrated and blown toward the dustproof net 5 through the air guide shell 405. After the dust on the surface of the dustproof net 5 is loosened by the cam 302, the airflow blown by the air pump 401 can completely blow the dust away from the dustproof net 5 and discharge it through the front side of the ventilation shell 2. This achieves efficient and automatic removal of dust from the dustproof net 5, ensuring the air intake efficiency and air quality of the blower's outdoor unit 1, while reducing manual maintenance costs and extending the service life of the equipment.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
