Description

Technical Field

[0001] The utility model relates to the field of foam aluminum plates, in particular to a spray gun for open-pore foam aluminum plates. Background Art

[0002] Foamed aluminum is a material that has the characteristics of both metal and bubbles after adding additives to pure aluminum or aluminum alloy and undergoing a foaming process. Its production process is to send the molten aluminum alloy to the foaming box, inject gas to form liquid foam, and wait for the liquid foam to solidify to form the required shape. Foamed aluminum can be divided into three specifications: large pore size, medium pore size, and small pore size. Each specification is divided into single-sided open pores, double-sided open pores, and natural casting state (double-sided closed). The diverse specifications can provide designers with more room for diversified design. Combined with the excellent energy absorption, sound absorption and heat resistance of foamed aluminum, open-pore foam aluminum panels are very suitable as indoor and outdoor wall materials.

[0003] As a wall material, foam aluminum panels need to be painted and cleaned regularly, but the shape of open-pore foam aluminum panels with a large number of irregular holes brings great trouble to cleaning and spraying. In painting, brushing and dipping methods are limited by their large area, and there are disadvantages of consuming too much manpower and being difficult to operate. The commonly used spraying method is more suitable, but facing the complex surface shape of open-pore foam aluminum panels, existing spraying tools, such as fan-shaped spray guns, also have the defects of low coverage and uneven coating, especially in some holes. The inner side is not completely painted, and the appearance of the entire wall will be affected. At the same time, it is also difficult to find suitable cleaning tools to thoroughly and efficiently clean and maintain the surface of the open-pore foam aluminum panel. Utility Model Content

[0053] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0054] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0055] See also Figure 1-11 The first embodiment provides a spray gun for a perforated foam aluminum plate, which needs to be used in conjunction with a pump body and is used for surface spraying or cleaning of the perforated foam aluminum plate. The spray gun mainly includes: a spray gun body 100, a sliding control assembly 200, a transmission assembly 300 and a rotating nozzle 400, etc.

[0056] The spray gun body 100 is the outer shell structure of the spray gun for the open-cell foam aluminum plate of this embodiment. Figure 1-Figure 4 As shown in the figure, the spray gun body 100 is L-shaped, divided into a longer gun body portion 110 and a shorter handle portion 120, and an L-shaped channel 150 is provided in the spray gun body 100, and the liquid inlet of the L-shaped channel 150 is arranged on the end of the handle portion 120 away from the gun body portion 110; the liquid outlet of the L-shaped channel 150 is arranged on the end of the gun body portion 110 away from the handle portion 120, and a pipe head 155 extends outward from the outlet of the L-shaped channel 150. At the same time, a rectangular parallelepiped side case 115 integrally formed with the gun body portion 110 is provided on one side surface of the gun body portion 110, and a cavity is provided in the side case 115 for accommodating the transmission assembly 300 and the control assembly 600, etc.

[0057] like Figure 4-Figure 5As shown in the figure, a rectangular outer slide groove 123 is provided on the side where the gun body 110 and the handle 120 are connected, and near the inner corner where the two are connected; a cylindrical inner slideway 121 connected to the L-shaped channel 150 is also provided in the handle 120, and the diameter of the inner slideway 121 is larger than the L-shaped channel 150. By providing the outer slide groove 123 and the inner slideway 121, a sliding control component 200 adapted to the two is slidably provided in the handle 120, and the sliding control component 200 is used to slide and control the opening and closing of the L-shaped channel 150. Figure 6 As shown, the sliding control assembly 200 is mainly composed of an outer slider 240, a push piece 230, a slide bar 210 and an inner slider 220. The slide bar 210 is slidably embedded in a slide hole 127 provided on the surface of the handle portion 120 facing the liquid outlet, and extends into the inner slideway 121 through the slide hole 127. A cylindrical inner slider 220 is provided on one end of the slide bar 210 extending into the inner slideway 121, and the inner slider 220 is slidably embedded in the inner slideway 121, fitting with its inner wall, and the length of the inner slider 220 is greater than the diameter of the L-shaped channel 150. When it moves to the connection between the L-shaped channel 150 and the inner slideway 121, it can completely close the L-shaped channel 150, thereby controlling the entry of liquid. A push piece 230 roughly in the shape of a vertical plate is connected to one end of the slide bar 210 outside the handle portion 120. The push piece 230 is recessed inward on the side away from the handle portion 120, so as to facilitate the user to apply a pressing force to move the sliding control assembly 200. On the side of the push piece 230 close to the outer slide groove 123, a rectangular outer slide block 240 integrally formed with it is also provided. The outer slide block 240 is slidably embedded in the outer slide groove 123, thereby limiting the movement of the sliding control assembly 200 and preventing it from rotating left and right, which affects the use of the user. In addition, a spring 250 is also provided between the inner slide block 220 and the inner wall of the inner slideway 121. When the user releases the push piece 230, the spring 250 can rebound to keep the inner slide block 220 in the position of the closed L-shaped channel 150.

[0058] like Figure 2-Figure 3 As shown in the figure, the rotating spray head 400 is rotatably arranged at the liquid outlet of the L-shaped channel 150 at one end of the gun body 110 away from the handle 120, and its cross section is roughly fan-shaped, and a rotating cylinder 430 integrally formed with the rotating spray head 400 is arranged at one end of the liquid outlet of the L-shaped channel 150. Figure 3 As shown, the interior of the drum 430 is connected to the L-shaped channel 150, and the pipe head 155 is engaged in the drum 430, and the two can rotate relative to each other. Figure 7-Figure 11As shown in , a plurality of spray holes 410 are arranged on one end of the rotating nozzle 400 away from the pipe head 155, which are divided into eight groups along the circumference of the rotating axis of the rotating nozzle 400, with five holes in each group, which are connected to the inside of the rotating cylinder 430 of the rotating nozzle 400 through multiple groups of channels 420, and the multiple groups of channels 420 have different inclination angles relative to the rotating axis of the rotating nozzle 400. In this embodiment, the inclination angles of the multiple groups of channels 420 relative to the rotating axis of the rotating nozzle 400 increase in sequence from the first group to the eighth group in a clockwise direction, as shown in FIG. Figure 8-11 , showing the first, third, fifth and eighth groups of channels 420, wherein: the inclination angle α8 of the eighth group of channels> the inclination angle α5 of the fifth group of channels> the inclination angle α3 of the third group of channels> the inclination angle α1 of the first group of channels. It should also be noted that in one or more embodiments, the number of groups of injection holes 410, the number of holes in each group, and the gradient of the inclination change can be adaptively increased or decreased according to the specific shape and use needs of the rotating nozzle 400. By setting multiple groups of rotatable channels 420 at different angles, the spray gun achieves multi-directional coverage of various injection angles during the spraying process. Moreover, when the original non-rotating spray gun contacts the surface of the foam aluminum plate, in the direction perpendicular to the plate surface, the sprayed liquid generally only has the speed towards the ground brought by the acceleration of gravity, and flows downward; while the spray gun of this embodiment gives the sprayed liquid initial angular velocities in multiple directions during the rotation process, so when it contacts the surface of the foam aluminum plate, it can also further flow and cover in different directions to improve the liquid coverage rate.

[0059] like Figure 1-Figure 4 As shown in , the transmission assembly 300 is arranged between the gun body 110 and the rotating nozzle 400, driven by the control assembly 600, and drives the rotating nozzle 400 to rotate. Among them, the control assembly 600 is arranged in the side case 115, and mainly includes a motor 610, a power supply 630 and a moment switch 640 that are electrically connected in sequence; the transmission assembly 300 mainly includes a transmission rod 320 and a gear 322. One end of the transmission rod 320 is connected to the output end of the motor 610, and the other end is rotatably connected to the inner wall of the side case 115 through a bearing; the gear 322 is sleeved on the position of the transmission rod 320 near the other end, and a rack 432 is arranged on the outer wall of the rotating drum 430 to cooperate with it, and the gear 322 and the rack 432 are meshed with each other. In this embodiment, the rotating nozzle 400 is driven to rotate by the cooperation of the control assembly 600 and the transmission assembly 300.

[0060] A specific implementation of the present embodiment is: use the spray gun for the open-pored foam aluminum plate of the present embodiment to clean the wall surface of the open-pored foam aluminum plate. First, connect the liquid inlet of the L-shaped channel 150 on the handle 120 to the pump body, start the pump body, and draw a solution mixed with detergent through the pump body; then, press and push the push piece 230 of the sliding control assembly 200, and start the motor 610 to rotate and spray the mixed solution onto the wall surface of the open-pored foam aluminum plate. Since the rotating nozzle 400 can automatically spray at multiple angles, the user only needs to move the spray gun up, down, left, and right to quickly cover the entire wall surface with the mixed solution; then, release the push piece 230, replace the mixed solution drawn by the pump body with clean water, and perform the above-mentioned spraying operation again to wash away the mixed detergent, dust, stains, etc., and the wall surface can be cleaned.

[0061] In this embodiment, the spray gun for the perforated foam aluminum plate is provided with a spray gun body 100, a sliding control component 200, a transmission component 300 and a rotating nozzle 400, and cooperates with a plurality of rotatable channels 420 at different angles on the rotating nozzle 400. The spray gun achieves multi-directional coverage of the sprayed liquid at various spraying angles during the spraying process and increases the liquid coverage area, thereby solving the problem in the prior art that the perforated foam aluminum plate with a large number of irregular holes brings great troubles to cleaning and spraying, resulting in low and uneven coating coverage and difficult cleaning and maintenance.

[0062] Preferably, if Figure 5 As shown, in this embodiment, a switch hole 125 in the shape of a rectangular parallelepiped can be provided on the side wall of the outer slide groove 123 near the handle portion 120, and a protrusion 242 integrally formed with the handle portion 120 is provided on the side wall of the outer slide 240 near the handle portion 120, and the protrusion 242 is adapted to the shape of the switch hole 125, and a momentary switch 640 of the control component 600 is provided inside the switch hole 125. Therefore, when the sliding control component 200 is moved to the position of opening the L-shaped channel 150, the protrusion 242 will also press the momentary switch 640, thereby starting the control component 600 and driving the rotating spray head 400 to rotate. In this preferred mode, pressing the sliding control component 200 can simultaneously start the liquid inlet and rotation of the rotating spray head 400, making the operation of the spray gun of this embodiment more convenient.

[0063] Preferably, if Figure 1As shown, in this embodiment, since the rotary spray head 400 causes an increase in liquid splashing and affects the surrounding environment, a spray gun cover 500 with radial openings can also be fixedly arranged on one end of the side case close to the rotary spray head 400 to reduce the splashing of the liquid sprayed from the rotary spray head 400 to the surroundings. Furthermore, the minimum inclination angle between the side of the spray gun cover 500 and the rotating axis of the rotary spray head 400 is greater than the maximum inclination angle between the channel 420 and the rotating axis of the rotary spray head 400, that is, the eighth group of channel inclination angles α8 in this embodiment, thereby avoiding as much as possible that the liquid sprayed from the rotary spray head 400 directly contacts the inner side of the spray gun cover 500, thereby reducing the waste of liquid.

[0064] In addition, if Figure 2 As shown, the control assembly in this embodiment is also provided with a power regulator 620, which is electrically connected to the motor 610 and the power supply 630 to prevent the motor 610 from driving the rotating nozzle to rotate too fast. In one or more embodiments, the purpose of deceleration can also be achieved by providing a deceleration mechanism instead of the transmission rod 320.

[0065] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
