Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal spray gun technology, and in particular to a multi-angle adjustable dust removal spray gun. Background Technology
[0002] A dust removal spray gun is a cleaning tool that uses compressed air to generate a high-speed airflow to remove dust and particles from the surface of objects. It features non-contact cleaning, high-efficiency cleaning, and adjustable airflow. It is widely used in fields such as electronic equipment maintenance, machining, automobile repair, and mold cleaning. When using it, it is important to maintain an appropriate distance, wear protective equipment, and ensure that the compressed air is dry and clean to avoid damaging sensitive parts or causing safety hazards.
[0003] 1. In the existing technology, the direction of the nozzle in most dust removal spray guns cannot be adjusted independently during use. Operators need to rotate their wrists and arms to adjust the direction of the nozzle. However, when cleaning small gaps where the distance and angle of wrist and arm rotation are limited, it is difficult for operators to adjust the nozzle to the designated cleaning point, thus making it difficult to clean small gaps.
[0004] 2. In the existing technology, when using some spray guns, pressing the handle releases the nozzle from blocking the barrel, and gas is ejected from the output end of the spray gun. However, during this process, the air output of the spray gun can only be the maximum air output provided by the air pump. It is not possible to slightly adjust the air output of the nozzle according to the operator's own wishes and the usage scenario without adjusting the air pump. Furthermore, an excessively large air output cannot be adapted to the cleaning of all workpieces, thus causing some inconvenience to the operator when using the spray gun. Utility Model Content

[0007] A handle is rotatably connected to the lower right side of the gun body, a rotating block is rotatably connected above the handle, a lifting block is rotatably connected above the rotating block, and a sealing plug is fixedly connected above the lifting block.
[0008] According to the multi-angle adjustable dust removal spray gun, a positioning hole is provided on the upper part of the fixed tube, a first sealing ring is fixedly connected to the outer right end of the fixed tube, a fastening knob is threadedly connected to the upper left side of the telescopic tube, and a positioning bead is fixedly connected to the lower end of the fastening knob.
[0009] According to the multi-angle adjustable dust removal spray gun, the first sealing ring is tightly fitted with the inner wall of the telescopic tube, and the positioning bead corresponds to the positioning hole.
[0010] According to the multi-angle adjustable dust removal spray gun, a second sealing ring is fixedly connected to the left end of the first connecting tube, and the second sealing ring is tightly fitted to the right end of the telescopic tube.
[0011] According to the multi-angle adjustable dust removal spray gun, the adjusting device includes a first connecting ring, a first rotating rod rotatably connected to the front and rear sides of the first connecting ring, a rod body fixedly connected to the front of the first rotating rod, a rod body fixedly connected to the rear of the first rotating rod, a second rotating rod rotatably connected to the right side of the rod body, a second connecting ring rotatably connected to the right side of the second rotating rod, a butterfly knob threadedly connected to the front of the front rod body, and a butterfly knob threadedly connected to the rear of the rear rod body.
[0012] According to the multi-angle adjustable dust removal spray gun, the first connecting ring is fixedly connected to the first connecting pipe in a horizontal direction, and the second connecting ring is fixedly connected to the left end of the second connecting pipe in a horizontal direction.
[0013] According to the aforementioned multi-angle adjustable dust removal spray gun, the first longitudinal connecting ring is fixedly connected to the right end of the second connecting pipe, and the second longitudinal connecting ring is fixedly connected to the nozzle.
[0014] According to the multi-angle adjustable dust removal spray gun, an intermediate pipe is fixedly connected inside the gun body. The intermediate pipe is connected to the air inlet pipe and the fixed pipe. A valve chamber is fixedly connected to the middle of the intermediate pipe. The sealing block is slidably connected to the valve chamber. Return springs are fixedly connected to the front and rear sides of the lifting block.

[0016] This utility model has the following beneficial effects:
[0017] 1. Compared with existing technologies, this new technology allows operators to loosen the horizontal butterfly knob, enabling them to rotate the second connecting tube longitudinally around the first connecting ring. This causes the first flexible tube to deform accordingly, thus adjusting the longitudinal direction of the second connecting tube. Furthermore, loosening the vertical butterfly knob allows operators to rotate the second connecting tube laterally around the first connecting ring. This causes the second flexible tube to deform accordingly, thus adjusting the lateral direction of the nozzle. Through the combined effect of these two technologies, the longitudinal and lateral positions of the nozzle are adjusted, allowing operators to clean different areas without rotating their arms or wrists during the cleaning of small crevices.
[0018] 2. Compared with existing technologies, by pulling the handle backward, the operator moves the sealing block downward. At this time, a certain distance is created between the upper end of the sealing block and the upper part of the central hole of the valve chamber, connecting the front and rear sides of the valve chamber and realizing the delivery of gas. As the operator continues to pull the handle, the distance between the upper end of the sealing block and the upper part of the central hole of the valve chamber becomes larger, that is, the gas output is greater. This shows that the greater the degree to which the operator pulls the handle, that is, the further the handle moves backward, the greater the gas output, and vice versa. Thus, the gas output of the nozzle can be slightly adjusted without adjusting the air pump. Attached Figure Description

[0029] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0030] Reference Figure 1-6 This utility model discloses a multi-angle adjustable dust removal spray gun, comprising a gun body 1. An air inlet pipe 15 is fixedly connected to the bottom input end of the gun body 1, and a fixed pipe 2 is fixedly connected to the output end of the gun body 1. A positioning hole 3 is provided above the fixed pipe 2. A first sealing ring 4 is fixedly connected to the outer right end of the fixed pipe 2. A fastening knob 6 is threadedly connected to the upper left side of a telescopic pipe 5, and a positioning bead 7 is fixedly connected to the lower end of the fastening knob 6. The first sealing ring 4 is tightly fitted to the inner wall of the telescopic pipe 5, and the positioning bead 7 corresponds to the positioning hole 3. A telescopic pipe 5 is slidably connected to the right side of the fixed pipe 2, and a first connecting pipe is threadedly connected to the right side of the telescopic pipe 5. 8. A second sealing ring 10 is fixedly connected to the left end of the first connecting pipe 8. The second sealing ring 10 is tightly fitted to the right end of the telescopic pipe 5. An adjustment device 9 is arranged horizontally on the right side of the first connecting pipe 8. A first hose 11 is fixedly connected to the right side of the first connecting pipe 8. A second connecting pipe 12 is fixedly connected to the right side of the first hose 11. An adjustment device 9 is arranged vertically on the right side of the second connecting pipe 12. A second hose 13 is fixedly connected to the right side of the second connecting pipe 12. A nozzle 14 is fixedly connected to the right side of the second hose 13. Anti-slip pads 16 are fixedly connected to the front and rear sides of the gun body 1. A retaining ring 17 is fixedly connected to the top of the gun body 1.
[0031] The above structure, by providing a first sealing ring 4, and the first sealing ring 4 being tightly fitted to the inner wall of the telescopic tube 5, ensures that after the operator has adjusted the telescopic tube 5, the tight contact between the first sealing ring 4 and the inner wall of the telescopic tube 5 makes the fixed tube 2 and the telescopic tube 5 relatively sealed, that is, gas will not leak out from the connection between the telescopic tube 5 and the fixed tube 2.
[0032] By providing a second sealing ring 10, which is fixedly connected to the first connecting pipe 8 and in close contact with the right end of the telescopic pipe 5, gas will not leak from the connection between the first connecting pipe 8 and the telescopic pipe 5 when the operator threads the first connecting pipe 8 and the telescopic pipe 5 together, thanks to the action of the second sealing ring 10.
[0033] By rotating the fastening knob 6, the positioning bead 7 is moved away from the positioning hole 3. At this time, the operator can move the telescopic tube 5 left and right. After adjustment, continue to rotate the fastening knob 6 to reinsert the positioning bead 7 into the corresponding positioning hole 3, so as to achieve the purpose of extending and shortening the overall device.
[0034] By incorporating anti-slip pads 16, the friction between the device and the operator's hand is increased during the operation, reducing the probability of slippage.
[0035] By incorporating a retaining ring 17, operators can hang the device in a designated location when not in use, reducing the risk of the entire device being damaged by being stepped on when placed on the ground.
[0036] The adjusting device 9 includes a first connecting ring 91, with a first rotating rod 92 rotatably connected to the front and rear sides of the first connecting ring 91. A rod body 93 is fixedly connected to the front of the first rotating rod 92, and a rod body 93 is fixedly connected to the rear of the first rotating rod 92. A second rotating rod 94 is rotatably connected to the right side of the rod body 93, and a second connecting ring 95 is rotatably connected to the right side of the second rotating rod 94. A butterfly knob 96 is threadedly connected to the front of the front rod body 93, and a butterfly knob 96 is threadedly connected to the rear of the rear rod body 93. The first connecting ring 91 is fixedly connected to the first connecting pipe 8 laterally, and the second connecting ring 95 is fixedly connected to the left end of the second connecting pipe 12 laterally. The first connecting ring 91 is fixedly connected to the right end of the second connecting pipe 12 longitudinally, and the second connecting ring 95 is fixedly connected to the nozzle 14 longitudinally.
[0037] The above structure reduces the resistance between the butterfly knobs 96 on the front and rear sides and the first rotating rod 92 on the second rotating rod 94 by turning the butterfly knobs 96 on the front and rear sides. At this time, the operator can adjust the direction of the pipeline by rotating the second rotating rod 94 and the second connecting ring 95.
[0038] The first horizontal connecting ring 91 is fixedly connected to the first connecting pipe 8, and the second horizontal connecting ring 95 is fixedly connected to the left end of the second connecting pipe 12. This allows the operator to loosen the horizontal butterfly knob 96 and rotate the second connecting pipe 12 longitudinally with the first connecting ring 91 as the center. At this time, the first flexible hose 11 will deform accordingly, so that the longitudinal direction of the second connecting pipe 12 can be adjusted while the first flexible hose 11 is connected to the first connecting pipe 8 and the second connecting pipe 12.
[0039] The first longitudinal connecting ring 91 is fixedly connected to the right end of the second connecting pipe 12, and the second longitudinal connecting ring 95 is fixedly connected to the nozzle 14. This allows the operator to rotate the second connecting pipe 12 laterally with the first connecting ring 91 as the center when the operator loosens the longitudinal butterfly knob 96. At this time, the second hose 13 will deform accordingly, so that the nozzle 14 can be adjusted laterally when the second hose 13 is connected to the second connecting pipe 12 and the nozzle 14.
[0040] A handle 18 is rotatably connected to the lower right side of the gun body 1. A rotating block 19 is rotatably connected above the handle 18. A lifting block 20 is rotatably connected above the rotating block 19. A sealing plug 21 is fixedly connected above the lifting block 20. An intermediate pipe 23 is fixedly connected inside the gun body 1. The intermediate pipe 23 is connected to the air intake pipe 15 and the fixed pipe 2. A valve chamber 24 is fixedly connected to the middle of the intermediate pipe 23. The sealing plug 21 is slidably connected to the valve chamber 24. Return springs 22 are fixedly connected to the front and rear sides of the lifting block 20. The other end of the return spring 22 is fixedly connected to the upper inner surface of the gun body 1.
[0041] In the above structure, the operator pulls the handle 18 backward, causing the rotating block 19 to rotate in relation to the handle 18 and the lifting block 20. Simultaneously, the rotating block 19 pulls the sealing block 21 downward. As the sealing block 21 moves downward, a certain distance is created between the upper end of the sealing block 21 and the upper part of the central hole of the valve chamber 24. This connects the front and rear sides of the valve chamber 24, enabling gas delivery. Furthermore, as the operator pulls the handle 18, the distance between the upper end of the sealing block 21 and the upper part of the central hole of the valve chamber 24 increases, resulting in a larger gas output.
[0042] By providing a return spring 22, with its upper end fixedly connected to the gun body 1 and its lower end fixedly connected to the lifting block 20, when the operator releases their grip, the lifting block 20 returns to its original position due to the contraction of the return spring 22, meaning that the sealing block 21 is fully inserted into the valve chamber 24.
[0043] By providing a sealing plug 21, and a sealing layer on the outer surface of the sealing plug 21, and the sealing layer being made of silicone rubber, the silicone rubber, due to its unique silicon-oxygen bond structure, possesses high elasticity and low compression set, can tightly fit irregular surfaces, effectively prevent gas or liquid leakage, and is suitable for dynamic and static sealing scenarios. Furthermore, the sealing layer is tightly fitted with the valve chamber 24, thus achieving a seal between the sealing plug 21 and the valve chamber 24.
[0044] Working principle: When using this multi-angle adjustable dust removal spray gun, first adjust the horizontal adjustment device 9 and the vertical adjustment device 9 respectively so that the nozzle 14 points in the specified direction. Connect the air inlet pipe 15 to the external air pump through the pipe. Then, the operator pulls the handle 18 backward. By pulling the handle backward, a certain distance is created between the upper end of the sealing block 21 and the upper part of the central circular hole of the valve chamber 24. At this time, the front and rear sides of the valve chamber 24 are connected, so that the gas can be sprayed out.
[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
