Description

Technical Field

[0001] This utility model belongs to the field of spraying technology, and more specifically, it relates to a spraying device. Background Technology

[0002] Spraying equipment is a common tool in the spraying industry. There are various types of spraying equipment. One type works by spraying compressed air at the nozzle tip to create a negative pressure, which draws paint from the paint bottle. The compressed air then atomizes the paint and blows it onto the workpiece. However, current spraying equipment suffers from significant pressure loss after the compressed air reaches the nozzle tip, resulting in poor paint uniformity and affecting the overall spraying effect.

[0037] Combination Figure 1 , Figure 3 and Figure 4 A spraying device includes a main body 100, a spraying structure 200, a paint bottle 300, and an air pump 400.

[0038] The main body 100 includes a handle 110 and a nozzle 120. The two ends of the handle 110 are connected to the base 130 and the nozzle 120 respectively. One end of the nozzle 120 is provided with a mounting ring 121, and the other end of the nozzle 120 is provided with a nozzle 122.

[0039] A spraying structure 200 is disposed within the spray head 120, with one end extending to the nozzle 122. The spraying structure 200 is provided with an air jet channel 210 and a paint spraying channel 220, with the paint spraying channel 220 located above it. One end of the air jet channel 210 is inclined upwards, forming an angle of less than 90° with the paint spraying channel 220 to spray high-pressure airflow towards the outlet of the paint spraying channel 220. For example, the angle between the air jet channel 210 and the paint spraying channel 220 can be 30°, 45°, or 65°, etc.

[0040] The paint bottle 300 is detachably connected to the mounting ring 121 so that the outlet of the paint bottle 300 can be aligned with the paint spray channel 220. The paint bottle 300 can contain paint or pigments, etc.

[0041] An air pump 400 is located inside the handle 110 and is connected to the other end of the paint spray channel 220.

[0042] Specifically, the compressed gas generated by the air pump 400 is ejected from the jet channel 210 and forms a negative pressure at the outlet of the paint spraying channel 220, thereby causing the paint in the paint bottle 300 to be ejected from the paint spraying channel 220.

[0043] As can be seen, in the spraying device of this application, one end of the spraying structure 200 extends to the nozzle 122 of the spray head 120. The spraying structure 200 is provided with an air jet channel 210 and a paint spraying channel 220. One end of the air jet channel 210 is inclined upward and forms an angle of less than 90° with the paint spraying channel 220 to spray high-pressure airflow into the outlet of the paint spraying channel 220, so that sufficient negative pressure can be generated in the paint spraying channel 220. The paint bottle 300, which is set on the mounting ring 121 and aligned with the paint spraying channel 220, can spray paint from the nozzle 122 through the paint spraying channel 220. The paint spraying channel 220 can maintain sufficient negative pressure on the outlet side of the paint bottle 300 and can prevent the paint in the paint bottle 300 from dispersing before being sprayed out of the nozzle 122, thereby ensuring the uniformity of the sprayed paint and ensuring the spraying effect.

[0044] See Figure 3 and Figure 5 In order to further increase the negative pressure inside the paint spraying channel 220, the paint spraying structure is also provided with a connection hole 230, which connects the outlet of the paint spraying channel 220 with the outlet of the jet spraying channel 210, so that the paint spraying channel 220 can directly spray compressed gas to the outlet of the paint spraying channel 220.

[0045] In one embodiment, to ensure that the paint sprayed from the paint bottle 300 can be accurately sprayed from the spray channel 220, the spray channel 220 can be made coaxial with the mounting ring 121. It is understood that because the spray channel 220 is coaxial with the mounting ring 121, after the paint bottle 300 is installed with the mounting ring 121, the outlet of the paint bottle 300 can be coaxial with the spray channel 220, thereby ensuring that the paint sprayed from the paint bottle 300 can be accurately sprayed from the spray channel 220.

[0046] See Figure 3 and Figure 5 A first guide slope 240 can also be provided on the outer wall of the coating structure. The first guide slope 240 is used to guide the coating sprayed from the coating bottle 300 to the spraying channel 220.

[0047] In one embodiment, the paint spraying channel 220 extends to the side wall of the spraying structure 200 to form an opening, and the inner wall of the nozzle 122 is provided with a second guide slope 123. The second guide slope 123 guides the paint sprayed from the paint bottle 300 to the opening of the paint spraying channel 220 and enters the paint spraying channel 220.

[0048] Furthermore, a guide channel communicating with the paint spraying channel 220 can be formed between the first guide slope 240 and the second guide slope 123 to ensure that the paint sprayed from the paint bottle 300 can accurately enter the paint spraying channel 220.

[0049] Understandably, the above method can ensure that sufficient pressure is formed in the paint spraying channel 220, and at the same time, it can ensure that the paint sprayed from the paint bottle 300 can accurately enter the paint spraying channel 220.

[0050] See Figure 3 The spraying device may also include a connecting pipe 500, which is disposed inside the spray head 120. One end of the connecting pipe 500 is connected to the air pipe of the air pump 400, and the other end of the connecting pipe 500 is connected to the jet channel 210. It can be understood that the above structure facilitates the connection between the air pump 400 and the jet channel 210.

[0051] See Figure 1 and Figure 3 The spraying device may also include a button 600, which is located on the handle 110 and is connected to the air pump 400 to control the air supply of the air pump 400.

[0052] See Figure 1 and Figure 3 The spraying device may also include a base 130, which is connected to the end of the handle 110 away from the nozzle 120. When the spraying device is stationary, the base 130 can support the spraying device.

[0053] Furthermore, in one embodiment, the spraying device may also include a battery 700, which is disposed within the base 130 and electrically connected to the air pump 400 to provide power to the air pump 400. It is understood that the above method can fully utilize the space of the base 130, making the layout of the entire spraying device more reasonable and the structure more compact. At the same time, the battery 700 can also provide sufficient weight to the base 130, ensuring the stability of the base 130.

[0054] Furthermore, to improve the user's handling experience, the grip 110 can be tilted between the nozzle 120 and the base 130.

[0055] See Figure 1 and Figure 3 The spraying device may also include an adjusting wheel 800, which is rotatably mounted on the base 130 and located on the side of the base 130. The adjusting wheel 800 is electrically connected to the air pump 400 to control the amount of air output from the air pump 400. It can be understood that by adjusting the amount of compressed gas ejected by the air pump 400 through the adjusting wheel 800, the spraying volume and atomization effect can be controlled.

[0056] See Figure 3 In one embodiment, to make the spraying device more compact while ensuring sufficient support for the paint bottle 300 and preventing excessive pressure on the mounting ring 121 from causing damage, a receiving cavity 124 may be provided inside the spray nozzle 120, and the mounting ring 121 is disposed within the receiving cavity 124. The paint bottle 300 includes a bottle body and a nozzle connected to the bottle body. The nozzle is connected to the mounting ring 121, and the receiving cavity 124 can accommodate at least a portion of the bottle body.

[0057] Specifically, the nozzle and the mounting ring 121 can be threaded together to achieve a detachable connection.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
