Therefore, the terms used herein must be understood based on the description made herein.

[0028] A suspended multi-rudder self-balancing sprayer, such as Figure 1 As shown, it includes a base 100, a paint tank 200, a paint pump 300, a spray head 400 and a balancing device. The spray head 400 includes a spray head 410 for spraying paint. The paint tank 200, the paint pump 300 and the spray head 410 are arranged on the top of the base and are connected in series. Figure 1 or Figure 2 or Figure 3 As shown, the balancing device includes a telescopic rod 610, a tail assembly 620, a fan assembly 630, and a fan mounting bracket 640. The first end of the telescopic rod 610 is fixedly connected to the base 100. The tail assembly 620 is provided at the second end of the telescopic rod 610. A fan mounting bracket 640 is provided on the telescopic rod 610, located between the tail assembly 620 and the base 100, for mounting the fan assembly 630. The tail assembly 620 uses flowing air as power and applies a variable direction force to the telescopic rod 610 through self-adjustment. The fan assembly 630 is used to provide flowing air to the tail assembly 620, which serves as the power for the tail assembly 620 to apply torque to the base 100 via the telescopic rod 610. The telescopic rod 610 is provided with a locking mechanism to adjust and fix the length of the telescopic rod 610, thereby adjusting the length of the force arm through which the tail assembly 620 applies torque to the base 100.

[0029] In one embodiment, Figure 1 or Figure 2 or Figure 3 As shown, the tail assembly includes horizontal and vertical rudders. The horizontal and vertical rudders are arranged perpendicular to each other. The horizontal rudders are used to change the direction and / or magnitude of the horizontal force applied by the tail assembly to the telescopic rod. The vertical rudders are used to change the direction and / or magnitude of the vertical force applied by the tail assembly to the telescopic rod.

[0030] In one embodiment, Figure 1 or Figure 2 or Figure 3As shown, the nozzle mounting plate 120 is further included. The nozzle mounting plate 120 is used to mount the nozzle 410. The nozzle mounting plate 120 is vertically fixed on the base 100.

[0031] In one embodiment, Figure 2 or Figure 3 As shown, the first and second anti-collision bars 131, 134 are also included. The first and second anti-collision bars 131, 134 are fixedly connected to the base 100 and are located at the edge of the base 100 in the direction of the spraying direction of the nozzle 410. The first and second anti-collision bars 131, 134 are used to prevent the base 100 and the components mounted thereon from colliding with the wall during construction.

[0032] In one embodiment, Figure 1 or Figure 2 or Figure 3 As shown, elastic components (not shown) are provided at the ends of the first anti-collision rod 131 and the second anti-collision rod 134 to provide a buffering effect during collision.

[0035] In one embodiment, Figure 2 or Figure 3 As shown, the base 100 further includes a first hanging column 111, a second hanging column 112, and a third hanging column 113. The first hanging column 111, the second hanging column 112, and the third hanging column 113 are evenly arranged along the edge of the base 100 so that when the first hanging column 111, the second hanging column 112, and the third hanging column 113 are hoisted by the hoisting rope, the base 100 can remain horizontal.

[0036] In one embodiment, Figure 2 or Figure 3As shown, the base 100 further includes a fourth suspension column 114 disposed on the base 100. The first suspension column 111, the second suspension column 112, the third suspension column 113, and the fourth suspension column 114 are evenly disposed along the edge of the base 100 so that the base 100 can remain horizontal when the first suspension column 111, the second suspension column 112, the third suspension column 113, and the fourth suspension column 114 are hoisted by the hoisting rope.

[0037] In one embodiment, Figure 1 As shown, the paint tank 200 is provided with a stirring chamber 210 and a finished product chamber 220, as well as a paint channel 211 connecting the stirring chamber 210 and the finished product chamber 220. A paint inlet 212 is provided on the wall of the stirring chamber 210 for adding paint into the stirring chamber 210. A stirring portion 231 and a centrifuge 232 are provided in the stirring chamber 210, and the stirring portion 231 and the centrifuge 232 are coaxially connected.

The paint tank 200 also includes a stirring motor 230. The output shaft of the stirring motor 230 is coaxially connected to the stirring portion 231 and the centrifuge 232. The distance between the cavity bottom surface of the finished product chamber 220 and the base 100 is smaller than the distance between the cavity bottom surface of the stirring chamber 210 and the base 100. The wall of the finished product cavity 220 is provided with a paint outlet 221 for outputting the stirred paint to the paint pump 300. The paint outlet 221 is provided close to the cavity bottom surface of the finished product cavity 220.

[0038] In one embodiment, Figure 1 As shown, the nozzle head 400 further includes a platform 411. The nozzle 410 is disposed on the platform 411. The platform 411 is elastically connected to the base 100 via a spring assembly 420.

[0039] In one embodiment, Figure 1 or Figure 2 or Figure 3 As shown, a camera assembly 500 is also provided on the nozzle mounting plate 120. The camera assembly 500 is used to obtain a wall image in the spraying direction of the nozzle 410.

[0040] In one embodiment, Figure 2 or Figure 3 As shown, the suspension ropes are connected to the first suspension post 111, the second suspension post 112, the third suspension post 113 and the fourth suspension post 114 respectively, so as to lift the sprayer of the present application and keep the base 100 of the sprayer of the present application level. Figure 4 or Figure 5 As shown, the first anti-collision rod 131 and the second anti-collision rod 134 fixedly connected to the base 100 are close to the wall so that the sprayer of the present application always maintains a certain distance from the wall, preventing damage caused by the sprayer hanging and shaking and colliding with the wall.

[0041] The suspended multi-rudder self-balancing sprayer provided above comprises a paint spraying system formed by disposing a paint tank 200, a paint pump 300, and a spray head 410 in series on a base 100. A balancing device is provided, comprising a telescopic rod 610, a tail assembly 620, a fan assembly 630, and a fan mounting bracket 640. The first end of the telescopic rod 610 is fixedly connected to the base 100; the tail assembly 620 is disposed on the second end of the telescopic rod 610. A fan mounting bracket 640 is disposed on the telescopic rod 610 between the tail assembly 620 and the base 100, and is mounted on the fan assembly 630 to provide flowing air to the tail assembly 620, which serves as the power for the tail assembly 620 to apply torque to the base 100 via the telescopic rod 610. The tail assembly 620 can apply an opposing torque to the base 100 via the telescopic rod 610 to offset the torque caused by the recoil force of the spray head 410 when spraying paint, allowing the sprayer to maintain balance when suspended on a building exterior wall for construction work, thereby improving spraying accuracy. Furthermore, the sprayer is simple in structure, easy to implement, lightweight, safe, convenient, and has a low manufacturing cost.

[0042] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
