Abstract
Description
Technical Field
[0001] This utility model relates to a spraying tool, specifically a portable spraying device. Background Technology
[0002] When compressed air is ejected from the air cap at the front of the paint spray gun, a low-pressure zone lower than atmospheric pressure is created in front of the paint nozzle connected to it. This pressure difference at the nozzle draws the paint out of the paint tank and, under the action of the high-speed jet force of the compressed air, atomizes it into particles and sprays it onto the surface of the object to be coated.
[0003] Currently, spray guns adjust the spraying range by controlling the position of the nozzle to control the spray volume and angle. However, with the current control method, a large amount of paint still flies out of the desired area. Utility Model Content
[0004] To address the technical problem that current methods of controlling the spraying range result in a large amount of paint flying out of the desired area, this invention provides a portable spraying device. By adjusting the angle of the baffle through a slider and connecting rod, it has the advantage that after adjusting the spray gun's spraying range, paint will not be sprayed into areas outside the desired range.
[0005] The technical solution of this utility model is:
[0006] A portable spraying device, comprising:
[0007] The spray gun body has a handle, a container, a pressurizer, and a barrel, with a nozzle at the end of the barrel;
[0008] A baffle, one end of which is rotatably connected to the end of the gun barrel;
[0009] The slider is slidably mounted on the barrel and is located on the same side of the barrel as the baffle, and can reciprocate along the length of the barrel.
[0010] The connecting rod has one end rotatably located in the middle of the baffle, and the other end rotatably connected to the end of the slider;
[0011] The top and bottom of the barrel are symmetrically equipped with baffles, sliders and connecting rods.
[0012] Optionally, the top and bottom of the barrel are respectively provided with a groove along its length, and two sliders are respectively slidably disposed in the two grooves.
[0013] Optionally, both sliders are threaded on the outside, and the spraying device also includes:
[0014] The nut is rotatably located in the middle of the barrel and engages with the threads on the two sliders.
[0015] Optionally, the nozzle extends beyond the end of the barrel, two baffles cover the top and bottom of the nozzle, and side plates are provided on both sides of the barrel.
[0016] Optionally, the baffle has a V-shaped structure, and the angle of the baffle is greater than 90° and less than 180°, with the nozzle located between the two baffles on the side where the angle of the baffle is greater than 90° and less than 180°.
[0017] Optionally, the baffle located at the bottom of the barrel is a collecting plate, which has a V-shaped structure and a through hole in the middle.
[0018] The spraying device also includes:
[0019] One end of the guide tube is located on the through hole in the middle of the collecting plate;
[0020] The recycling bottle is connected to the other end of the conduit.
[0021] Optionally, the spray gun body is provided with a support rod, and the end of the support rod has a connector. The end of the conduit away from the collection plate is connected to the connector, and the connector is detachably connected to the recycling bottle.
[0022] Optionally, an annular plate is fitted onto the nozzle, the interior of which has an arc-shaped surface structure.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] A slider is installed on the barrel of the spray gun body, allowing the slider to reciprocate along the length of the barrel. During the movement of the slider, a connecting rod rotates around one end of the slider at the end of the slider. The other end of the connecting rod then pulls a baffle to rotate at the end of the barrel, thereby moving the end of the baffle away from the barrel up or down. By synchronously driving the two baffles together through two sliders 30 and two connecting rods, the ends of the two baffles can be moved closer or further apart, thus controlling the spray angle when the nozzle is working.
[0025] Since the spray angle is controlled by a baffle away from the nozzle tip in this technical solution, compared with the prior art, this control method will not cause paint problems in areas outside the required range. Attached Figure Description

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0033] Example
[0034] See Figure 1 and Figure 2This embodiment discloses a portable spraying device, including a spray gun body 10, a baffle 20, a slider 30, and a connecting rod 40. The spray gun body 10 has a handle 11, a container 12, a pressurizer 13, and a barrel 14. The handle 11 includes a grip and a pressable spray valve 15. The pressurizer 13 includes a reciprocating piston. The container 12 is filled with paint for spraying and is detachably disposed in the middle of the spray gun body 10. A nozzle 16 is provided at the end of the barrel 14, and the nozzle 16 is connected to the container 12 and the toggle switch 15 of the spray valve.
[0035] Specifically, the baffle 20 is rotatably mounted on the end of the barrel 14, near the upper part of the barrel 14. The slider 30 is slidably mounted on the barrel 14 and can reciprocate along the length of the barrel 14. The end of the slider 30 is rotatably connected to one end of the connecting rod 40, and the other end of the connecting rod 40 is rotatably connected to the middle of the baffle 20. The connecting rod 40 has a bent structure. In addition, the slider 30, the connecting rod 40, and the baffle 20 are symmetrically arranged at the top and bottom of the barrel 14.
[0036] A slider 30 is installed on the barrel 14 of the spray gun body 10, and the slider 30 can reciprocate along the length of the barrel 14. During the movement of the slider 30, the connecting rod 40 rotates around one end of the slider 30, and the other end of the connecting rod 40 drives the baffle 20 to rotate at the end of the barrel 14, thereby driving the end of the baffle 20 away from the barrel 14 to move up or down. By synchronously driving the two baffles 20 with the two sliders 30 and the two connecting rods 40, the ends of the two baffles 20 can be moved closer or further apart, thus controlling the spray angle when the nozzle 16 is working.
[0037] Since the spray angle is controlled by a baffle 20 located away from the end of the nozzle 16 in this technical solution, compared with the prior art, this control method will not cause paint problems in areas outside the required range.
[0038] In one specific embodiment:
[0039] The top and bottom of the barrel 14 are respectively provided with a groove 17 along its length, and two sliders 30 are respectively slidably disposed in the two grooves 17.
[0040] The entire barrel 14 is cylindrical, and the side of the slider 30 located outside the slide groove 17 is also arc-shaped. A threaded structure is provided on the arc-shaped side of the two sliders 30, and a nut 50 is rotatably disposed in the middle of the barrel 14. The nut 50 matches the threads on the two sliders 30.
[0041] In this embodiment, the slide groove 17 is provided to limit the movement trajectory of the slider 30 on the barrel 14 and to limit the displacement distance of the slider 30. By providing the nut 50, the nut 50 can be rotated when the slider 30 needs to be moved. Utilizing the threaded engagement between the nut 50 and the slider 30, the two sliders 30 can be synchronously driven to move within the two slide grooves 17, while also allowing for more precise control of the opening angle of the two baffles 20.
[0042] In another specific embodiment:
[0043] The nozzle 16 extends from the end of the barrel 14, and two baffles 20 cover the top and bottom of the nozzle 16. Side plates 60 are also provided on both sides of the barrel 14. By setting the side plates 60, the sprayed paint is prevented from expanding outward from both sides, so that the sprayed paint is only sprayed on the vertical plane of adjustable width.
[0044] In this embodiment, the baffle 20 has a V-shaped structure, and the angle of the baffle 20 is greater than 90° and less than 180°. The nozzle 16 is located between the two baffles 20 on the side where the angle is greater than 90° and less than 180°. By setting the baffle 20 to a V-shape, the two baffles 20 can be closed under the drive of the connecting rod 40, thus enclosing the entire nozzle 16 and protecting the nozzle 16 when the spraying device is not in use.
[0045] In another specific embodiment:
[0046] The spraying device also includes a conduit 80 and a recycling bottle 90. The baffle 20 located at the bottom of the gun barrel 14 serves as a collection plate, and has a through hole in its center. One end of the conduit 80 is positioned over this through hole, and the end of the conduit 80 is sealed to the surrounding area of the through hole. The other end of the conduit 80 is connected to the opening of the recycling bottle 90, which is located below the collection plate.
[0047] In this embodiment, since the two baffles 20 block the paint, some paint will be blocked between the two baffles 20. Under the action of gravity, this part of the paint will gather at the through hole in the middle of the collection plate and enter the recycling bottle 90 through the conduit 80, thereby achieving the purpose of recycling.
[0048] In another specific embodiment:
[0049] The spray gun body 10 is equipped with a support rod 18, and the end of the support rod 18 has a connector. The end of the conduit 80 away from the collection plate is connected to the connector, and the connector is detachably connected to the recycling bottle 90. The connector has a channel in the middle, one end of which communicates with the conduit 80, and the other end can be detachably connected to the opening of the recycling bottle 90. This structure facilitates the installation and removal of the recycling bottle 90, and also facilitates the fixing of the recycling bottle 90's position.
[0050] In another specific embodiment:
[0051] An annular plate 19 is fitted onto the nozzle 16, and the interior of the annular plate 19 has an arc-shaped surface structure. By setting the annular plate 19, the amount of paint reflected back to the nozzle after being sprayed onto the baffle 20 is reduced, thereby increasing the recovery rate.
[0052] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
