The air inlet end 21 is used to communicate with a gas supply device. The vibration part 30 is arranged on the box body 10. The vibration part 30 has a vibration end 301 and a connection end 302 which are arranged oppositely. The vibration end 301 is arranged close to the air outlet end 22, and the vibration end 301 is used to vibrate an object.

[0036] Applying the technical solution of the present utility model, the box body 10 has a receiving cavity 11. The nozzle 20 and the vibration part 30 are arranged on the box body 10. The nozzle 20 has an air inlet end 21 and an air outlet end 22. The air inlet end 21 is communicated with a gas supply device. The vibration end 301 of the vibration part 30 is arranged close to the air outlet end 22 of the nozzle 20, and the vibration end 301 can vibrate an object. Through the above arrangement, when the nozzle 20 blows the impurities on the object, at the same time, the vibration end 301 can vibrate the object blown by the nozzle 20, so as to vibrate the impurities that are difficult to be blown off by the nozzle 20 on the object or the impurities that are stuck or adhered in the gap, so as to vibrate the impurities to be loose on the object. At this time, combined with the nozzle 20, the loose impurities are blown off from the object, greatly improving the cleaning effect of the dust blowing device on the impurities on the object.

[0037] Among them, the vibration end 301 can be set as a vibrating structure to realize the vibration of the impurities on the object. The vibration end 301 can also be set to be telescopic or swingable relative to the connection end 302, as long as it can realize the vibration of the object.

[0038] Specifically, the vibrating part 30 is movably arranged on the box body 10 through the connecting end 302, so that the vibrating effect of the vibrating part 30 on the object is better. The dust blowing device further includes a driving part 40. The driving part 40 is located in the accommodating cavity 11. The driving part 40 has a driving end, and the driving end is drivingly connected to the connecting end 302.

[0039] Specifically, the driving part 40 can be arranged as a motor, an oil cylinder or a hydraulic cylinder, etc.

[0040] Further, the vibrating part 30 includes a knocking head 31 and a vibrating rod 32. The vibrating rod 32 is movably arranged on the box body 10. The vibrating rod 32 is in the same extending direction as the air nozzle 20. The knocking head 31 is connected to one end of the vibrating rod 32. The knocking head 31 forms the vibrating end 301. The end of the vibrating rod 32 away from the knocking head 31 forms the connecting end 302. The driving part 40 is drivingly connected to the vibrating rod 32. Through the above settings, the driving part 40 drives the knocking head 31 to vibrate through the vibrating rod 32, so as to vibrate the object. The knocking head 31 can increase the contact area with the object, and then increase the vibrating area, thereby improving the cleaning effect on impurities.

[0041] In an embodiment of the present application, the driving part 40 can drive the vibrating rod 32 to vibrate, and then drive the knocking head 31 to vibrate the object.

[0042] In other embodiments of the present application, the driving part 40 can drive the vibrating rod 32 to swing relative to the object, and then drive the knocking head 31 to vibrate the object.

[0043] In some other embodiments of the present application, the driving part 40 can also drive the vibrating rod 32 to stretch and contract relative to the object, and then drive the knocking head 31 to vibrate the object.

[0044] In the present application, the shape of the knocking head 31 is not limited. Preferably, it is set as a spherical structure. In other embodiments, the knocking head 31 can also be set as a conical structure, a square structure or other special-shaped structures. Or it can be set as any shape according to different use scenarios.

[0045] Specifically, the outer periphery of the knocking head 31 can also be wrapped with a rubber sleeve, so that the knocking force of the knocking head 31 can be softer. The rubber sleeve can buffer the force on the surface of the object and prevent the knocking head 31 from damaging the object when knocking the object.

[0046] Further, the dust blowing device further includes a transmission assembly, at least part of the transmission assembly is disposed in the accommodation chamber 11, the transmission assembly is located between the driving member 40 and the connection end 302, the transmission assembly is drivingly connected to the driving end, and the driving end can drive the knocking head 31 to approach or move away from the box body 10 through the transmission assembly. Through the above arrangement, the driving member 40 drives the knocking head 31 through the transmission assembly, so that the stability of the vibration of the knocking head 31 can be improved, and further the knocking head 31 can vibrate the object more powerfully, improving the cleaning effect of the dust blowing device on the impurities on the object.

[0047] Meanwhile, different transmission assemblies can be selected according to different application scenarios to achieve different vibration frequencies, and further different cleaning effects can be realized.

[0048] Such as Figure 2 and Figure 3 As shown, the transmission assembly includes a worm 51, a worm gear 52 and a rotating shaft 53. Among them, the worm 51 is drivingly connected to the driving end, and the extending direction of the worm 51 is the same as the extending direction of the vibrating rod 32.

The rotating shaft 53 is rotatably disposed on the box body 10, the worm gear 52 is fixed on the rotating shaft 53, and the rotating shaft 53 rotates synchronously with the worm gear 52. With such an arrangement, the transmission is carried out through the cooperation of the worm gear 52 and the worm 51, the structure is simple and the assembly is compact, the driving speed of the driving end can be reduced, so that the knocking head 31 can vibrate the object more stably, improving the cleaning effect.

[0049] In the present application, the dust blowing device further includes a limiting assembly, and the limiting assembly is disposed between the vibrating rod 32 and the box body 10 to guide the moving direction of the knocking head 31. Through the above arrangement, the moving direction of the knocking head 31 can be guided, and it can be avoided that the position and direction of the knocking head 31 are different or change each time it approaches the object, resulting in a poor vibration effect on the object.

[0050] Further, the transmission assembly further includes a connecting rod 54, one end of the connecting rod 54 is connected to the rotating shaft 53, the other end of the connecting rod 54 is hinged to the connection end 302, and the rotating shaft 53 drives the connection end 302 to rotate around the rotating shaft 53 through the connecting rod 54. With such an arrangement, the connection end 302 is driven to rotate around the rotating shaft 53 through the connecting rod 54 to drive the knocking head 31 to approach or move away from the object, thereby realizing the vibration of the object, so that the knocking frequency of the knocking head 31 can be more regular, further improving the regularity and stability of the force of the entire dust blowing device, and at the same time improving the cleaning effect of the impurities on the object.

[0051] In other embodiments of the present application, the transmission assembly can also be arranged as a link mechanism, a gear mechanism or a gear-rack transmission.

[0052] Such as Figure 4As shown, the limiting component includes a support plate 61 and a sleeve 62. Among them, the support plate 61 has a support section 611 and an extension section 612. The extension section 612 has the same extension direction as the nozzle 20. One end of the extension section 612 is connected to the box body 10. The extension direction of the support section 611 has an angle with the extension direction of the extension section 612. The support section 611 is located above the extension section 612, and the extension section 612 is located below the nozzle 20. In this way, the extension section 612 can also pre-support the nozzle 20. When the nozzle 20 shakes, the extension section 612 can prevent the nozzle 20 from falling or shaking downward by too large an angle.

[0053] In this application, the specific structure of the limiting component is not limited. The limiting component can also be set as a limiting plate, placed above and below the vibrating part 30 to limit the vibration direction and position of the striking head 31. A locking structure can also be provided on the connecting rod 54 to limit the rotation angle of the connecting rod 54 relative to the rotating shaft 53, or the connecting end 302 relative to the connecting rod 54.

[0054] Among them, the sleeve 62 is rotatably connected to the support section 611. The rotation axis of the sleeve 62 is perpendicular to the extension direction of the vibrating rod 32. The sleeve 62 is located in the middle of the vibrating rod 32, and the vibrating rod 32 passes through the sleeve 62. And there is a gap between the vibrating rod 32 and the inner wall of the sleeve 62 to enable the vibrating rod 32 to perform reciprocating telescopic motion in the sleeve 62. Through the above settings, the sleeve 62 can limit and guide the vibrating rod 32 while also cooperating with the support section 611 to support the vibrating rod 32 to ensure the stability of the movement of the vibrating rod 32 and further improve the vibration effect of the vibrating part 30 on the object.

[0055] Preferably, the sleeve 62 is rotatably connected to the support section 611 through a support shaft 621. The support shaft 621 is fixedly penetrated through the support section 611, and the sleeve 62 is rotatably connected to the support shaft 621. The extension section 612 is set as a flat plate structure, so that the support section 611 and the box body 10 can be stably connected. The support section 611 is a channel steel structure. With this setting, the structure is simple and the cost is saved. The extension section 612 and the support section 611 can be connected by welding. At the same time, the channel steel structure can also limit the nozzle 20 in the horizontal direction to prevent the nozzle 20 from shaking excessively when purging an object. In other embodiments, the support section 611 and the extension section 612 can also adopt an integral forming process. In this way, the structural strength of the limiting component can be further improved.

[0056] Specifically, there are two sets of the vibration part 30 and the sleeve 62 respectively. The sleeve 62 is arranged corresponding to the vibration part 30 one by one. The two vibrating rods 32 are respectively located at both ends of the rotating shaft 53. The two sets of sleeves 62 are respectively rotatably arranged on both sides of the supporting section 611. The rotating shaft 53 can drive the two knocking heads 31 to alternately knock the article. Through the above arrangement, the two knocking heads 31 alternately knocking the article can further improve the vibration effect of the vibration part 30.

[0057] Furthermore, there are also two connecting rods 54. The two connecting rods 54 are respectively arranged on both sides of the rotating shaft 53, and there is an included angle in the extending direction of the two connecting rods 54 towards the connecting end 302. Specifically, the included angle can be set to 5°, 30°, 66° or 88°, etc. Preferably, the included angle is 180°. In this way, the vibration frequency of the knocking head 31 can be regular and periodic, and the cleaning effect is better. Moreover, when the vibration part 30 vibrates, the forces on both sides of the box body 10 can be more balanced, improving the working stability of the blowing and cleaning device.

[0058] As Figure 1 shown, the dust blowing device further includes a handle 70. The handle 70 is arranged on the side of the box body 10 away from the vibration part 30. Specifically, the handle 70 is fixedly connected to the box body 10 through a connecting frame 90.

And the connecting frame 90 can increase the contact area between the handle 70 and the box body 10, improving the connection stability between the handle 70 and the box body 10.

[0059] Furthermore, the connecting frame 90 adopts a channel steel structure, and the size of the connecting frame 90 is adapted to the box body 10. In this way, it is convenient to limit the movement of the box body 10 during use. The handle 70 is set as a round rod structure, which is convenient for the user to hold.
