Description

Technical Field

[0001] The utility model relates to the technical field of sprayers, in particular to an air outlet structure of a sprayer. Background Art

[0002] In the production process of rubber products, due to mold making and operation reasons, the rubber surface is often uneven and has a certain degree of stickiness. In order to ensure product quality, the mold needs to be cleaned with water using a sprayer, and the product needs to be sprayed with a release agent when demoulding. However, the traditional sprayer outlet structure has problems such as uneven spraying, limited coverage, and inconvenient adjustment, which affects the spraying effect and efficiency.

[0003] In view of this, we propose a sprayer air outlet structure. Utility Model Content

[0004] The utility model aims to provide an air outlet structure for a sprayer to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, on the one hand, the utility model provides a spray machine air outlet structure, including an air outlet duct, the top of the air outlet duct is fixedly connected to a fixing ring, the top of the fixing ring is rotatably connected to a first rotating arc ring, the inner side of the first rotating arc ring is rotatably connected to a second rotating arc ring, a rotating rod is provided on the inner side of the air outlet duct, the outer wall of the rotating rod is provided with a guide plate, and the lower end outer wall of the rotating rod is fixedly connected to a plurality of fan blades.

[0006] As a preferred embodiment of the utility model, a plurality of semicircular holes are provided on the outer wall of the first rotating arc ring, and an even-numbered circular array of the semicircular holes is distributed on the first rotating arc ring.

[0007] As a preferred embodiment of the utility model, limiting blocks are fixedly connected to both sides of the outer wall of the second rotating arc ring, the diameter of the limiting blocks matches the diameter of the semicircular holes, and the limiting blocks are symmetrically distributed on the outer wall of the second rotating arc ring with the rotating rod as the symmetry axis.

[0008] As a preferred embodiment of the utility model, a mist outlet is fixedly connected to the top of the second rotating arc ring, and the mist outlet is trumpet-shaped.

[0009] As a preferred embodiment of the present invention, the first rotating arc ring and the second rotating arc ring are both hollow inside, and the inner wall diameter of the first rotating arc ring is the same as the outer wall diameter of the second rotating arc ring, and the outer wall of the first rotating arc ring and the outer wall of the second rotating arc ring are both arc-shaped.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. In the air outlet structure of the sprayer, after the sprayer generates mist and it flows into the air outlet duct, the rotating rod is driven by electricity to rotate, and the fan blades are driven to rotate to form a wind direction toward the mist outlet, and the flow is guided by the guide plate to flow into the No. 1 rotating arc ring. At this time, if the No. 1 rotating arc ring is rotated to change the position of the mist outlet, and at the same time, when the mist flows to the No. 2 rotating arc ring, the rotation of the No. 2 rotating arc ring changes the position of the mist outlet again. When limited by the limit block and the semicircular hole, the air outlet duct can be prevented from being blocked, and the flow of the air outlet duct can be prevented from being reduced, and the mist is evenly sprayed on the rubber mold for demoulding.

[0019] See also Figure 1-3 As shown, this embodiment provides an air outlet structure of a sprayer, including an air outlet duct 1, a fixed ring 11 is fixedly connected to the top of the air outlet duct 1, a first rotating arc ring 2 is rotatably connected to the top of the fixed ring 11, a second rotating arc ring 3 is rotatably connected to the inner side of the first rotating arc ring 2, a rotating rod 4 is arranged on the inner side of the air outlet duct 1, a guide plate 42 is sleeved on the outer wall of the rotating rod 4, a plurality of fan blades 41 are fixedly connected to the outer wall of the lower end of the rotating rod 4, the fan blades 41 are used for guiding wind and are brought into the first rotating arc ring 2 by the guide plate 42.

[0020] A plurality of semicircular holes 21 are provided on the outer wall of the No. 1 rotating arc ring 2, and an even-numbered circular array of the semicircular holes 21 is distributed on the No. 1 rotating arc ring 2. Limiting blocks 31 are fixedly connected on both sides of the outer wall of the No. 2 rotating arc ring 3. The diameter of the limiting blocks 31 matches the diameter of the semicircular holes 21, and the limiting blocks 31 are symmetrically distributed on the outer wall of the No. 2 rotating arc ring 3 with the rotating rod 4 as the axis of symmetry. During the rotation of the No. 2 rotating arc ring 3, the limiting blocks 31 will be blocked by the semicircular holes 21.

[0021] A mist outlet 32 ​​is fixedly connected to the top of the second rotating arc ring 3. The mist outlet 32 ​​is trumpet-shaped and is used to form and guide wind flow, which helps to enhance the intensity and coverage of the air flow.

[0022] The first rotating arc ring 2 and the second rotating arc ring 3 are both hollow inside, and the inner wall diameter of the first rotating arc ring 2 is the same as the outer wall diameter of the second rotating arc ring 3, and the outer wall of the first rotating arc ring 2 and the outer wall of the second rotating arc ring 3 are both arc-shaped.

[0023] How it works

[0024] like Figure 1-2 As shown, after the sprayer generates mist and flows into the air outlet duct 1, the rotating rod 4 is driven by electricity to rotate, and the fan blades 41 are driven to rotate to form a wind direction toward the mist outlet 32. At the same time, the guide plate 42 is used to guide the airflow, and its main function is to adjust the intensity and direction of the airflow, and then it flows into the No. 1 rotating arc ring 3. At this time, if the No. 1 rotating arc ring 2 is rotated, the position of the mist outlet 32 ​​can be preliminarily changed to change the spray position. At the same time, when the mist flows toward the No. 2 rotating arc ring 3, if the No. 2 rotating arc ring 3 is rotated at this time, it rotates inside the No. 1 rotating arc ring 2. At the same time, when the No. 2 rotating arc ring 3 rotates at an angle that is too large, the air outlet duct 1 may be blocked. When limited by the limit block 31 and the semicircular hole 21, the air outlet duct 1 can be prevented from being blocked, and the flow rate of the air outlet duct 1 can also be prevented from being reduced.
