In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the embodiments of the present invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

Fig. 1 is a schematic structural diagram of an inkjet device according to an embodiment of the present invention; FIG. 2 is a schematic cross-sectional structure diagram of the inkjet main body in the inkjet device shown in FIG. 1; FIG. 3 is a schematic view of the nozzle structure of the inkjet device shown in FIG. 1.

Referring to fig. 1 to 3, the inkjet device includes: the spray painting device comprises a spray painting main body part 1, a material passage 3 and an air passage 4, wherein the material passage 3 and the air passage 4 are positioned in the spray painting main body part 1, the material passage 3 is used for conveying spray painting materials, and the air passage 4 is used for conveying compressed air; the nozzle 2 is positioned at one end of the inkjet main body part 1, the nozzle 2 is communicated with the outlet 32 of the material passage 3, the nozzle 2 is communicated with the outlet 42 of the air passage 4, the side wall of the nozzle 2 is provided with an opening 21, and the opening 21 penetrates through the inner surface and the outer surface of the nozzle 2.

The inkjet device provided in the present embodiment will be described in detail below with reference to the accompanying drawings.

Materials for spray painting enter the spray painting device from the inlet 31 of the material passage 3, and the spray painting materials can be viscous ink; air enters the spray painting device from an inlet 41 of the air passage 4, and the air entering the spray painting device is compressed air flowing at a high speed; the air may be a mixed gas or a single gas.

After entering the spray painting device, the compressed air is rapidly sprayed out through the outlet 42 of the air passage 4, and the rapid spraying of the compressed air can generate a siphon effect, so that the materials in the material passage 3 are driven to flow out; and the high-speed flowing compressed air can lead the flowing materials to be atomized, the continuous air flow continuously brings the materials out, and the materials are sprayed out of the spray painting device through the nozzle 2. The nozzle 2 can be used for controlling the spraying direction of the material to avoid sputtering of the material.

It will be appreciated that the above-described siphon effect means that the high velocity flow of air causes a pressure reduction in its flow path, so that the pressure at the outlet 32 of the material passageway 3 is less than the pressure at the inlet 31, and the material is squeezed out due to the pressure difference.

In this embodiment, the material passage 3 is located on one side of the air passage 4 away from the side wall of the inkjet main body part 1, that is, the air passage 4 is located outside the material passage 3; in other embodiments, the material passage is located on the side of the air passage adjacent to the side wall of the inkjet main body, i.e. the material passage is located outside the air passage.

In this embodiment, the side wall of the nozzle 2 has an opening 21, and the opening 21 penetrates the inner surface and the outer surface of the nozzle 2. Because the air flowing in the air passage 4 is compressed air, and the pressure inside the compressed air is greater than the atmospheric pressure, therefore, when the air flow and the materials are sprayed out from the nozzle 2, part of the compressed air can be discharged from the opening 21, and the air pressure of the air flow in the nozzle 2 is reduced, so that the difference between the air pressure of the emergent air flow finally sprayed out from the nozzle 2 and the atmospheric pressure is smaller, which is beneficial to avoiding the generation of cyclone at the outlet of the nozzle, thereby avoiding the influence of the cyclone on the spraying shape of the materials, being beneficial to enabling the sprayed materials to be in a thin line shape, realizing the uniform spraying and accurate spraying of a target spraying area, and further realizing the spraying and painting of fine characters and fine patterns; secondly, the air pressure of the air flow in the nozzle 2 is reduced, so that the situation that the emergent air flow blows away materials sprayed in a target area is avoided, and the uniform spraying of the target spraying area is further realized.

It will be appreciated that since the air in the nozzle 2 is compressed air, the air pressure of the air flow is greater than the atmospheric pressure, and when the air flows out of the nozzle 2, an air pressure difference is formed between the air and the surrounding uncompressed air. Due to the pressure difference, the compressed air starts to flow around, and further generates outward flowing vortex taking the emergent airflow as the axis, and the vortex is called cyclone.

In addition, the spray painting device provided by the embodiment can realize uniform spraying and accurate spraying on a target spraying area, so that under the condition that the target spraying effect is the same, spraying with a preset effect can be completed at a higher speed and with fewer materials, and waste of spray painting materials is reduced; and the problem of the flow melting of redundant materials to other positions caused by uneven spraying of the materials can be avoided.

It can be understood that if the side wall of the nozzle 2 has no opening 21, the difference between the air pressure of the emergent air flow and the atmospheric pressure is large, and the air flow can diffuse around due to the cyclone action after leaving the nozzle, so that the ejected material is umbrella-shaped, that is, the material in the middle area is more, the material in the peripheral area is less, and the material spraying is uneven; and because emergent airflow pressure is large, the material sprayed in the target area is easy to blow away, so that the sprayed material exceeds a preset boundary.

In this embodiment, the side wall of the nozzle 2 has a plurality of openings 21, and the plurality of openings 21 have the same horizontal position in the axial direction of the nozzle 2. Therefore, the air can be discharged at the same horizontal position at the same time, the air flow disorder caused by the fact that the air is discharged at different times is avoided, and the material is guaranteed to be in a thin line shape after being sprayed out of the nozzle 2.

It should be noted that, in other embodiments, the openings may not be located at the same horizontal position, but distributed irregularly on the side wall of the nozzle; in addition, if the openings in the same horizontal position are regarded as one group, the openings on the side wall of the nozzle can be provided with a plurality of groups, the openings in the same group are in the same horizontal position, the openings in different groups are in different horizontal positions, and the number of the openings in each group is more than or equal to 2.

In the present embodiment, the openings 21 are provided at equal intervals around the axis of the nozzle 2, and the number of the openings 21 is 4. Therefore, air can be discharged from all directions relatively uniformly, airflow disorder caused by nonuniform discharge is avoided, and the material is further ensured to be in a thin line shape after being sprayed out of the nozzle 2.

It should be noted that in other embodiments, the number of the openings may be 3 or any natural number greater than 4.

In this embodiment, the opening 21 penetrates the bottom surface of the nozzle 2, and the bottom surface of the nozzle 2 is connected to the quilt surface and the outer surface. Therefore, the formation of the cyclone can be further avoided or the range of the cyclone is reduced, so that the materials can be ejected in a columnar shape under the action of siphon and the continuous flow thrust of the external pump body, and can be further uniformly sprayed to a target area.

In this embodiment, the width of the opening 21 increases in the direction away from the inkjet main body 1. Therefore, the cyclone can be further prevented from being formed or the range of the cyclone is reduced, so that the material is in a thin line shape after being sprayed out of the nozzle, and the material can be sprayed to a target area more uniformly and accurately.

In this embodiment, the cross section of the nozzle 2 is circular in the axial direction of the nozzle 2, and the outlet radius of the nozzle 2 is larger than the inlet radius. Thus, the air pressure of the air flow at the outlet of the nozzle 2 is smaller than that at the inlet, so that the formation of cyclone is avoided, and the material can be sprayed to a target area more uniformly.

It should be noted that the plane of the outlet of the nozzle 2 and the plane of the inlet of the nozzle 2 may be parallel or may intersect.

In the present embodiment, the inner wall surface area of the nozzle 2 after opening is equal to or smaller than the side wall area of the opening 21 toward the axial center direction of the nozzle 2, in other words, the inner wall surface area of the nozzle 2 after opening is half or less of the inner wall surface area before opening. When the area of the side wall of the opening 21 facing the axial center direction of the nozzle 2 is within this range, the opening 21 can better discharge the gas, and is favorable for preventing the material from being splashed out of the opening.

In other embodiments, the surface area of the inner wall after the opening of the nozzle is more than half of the surface area of the inner wall before the opening.

Specifically, the pin 61 has a conical end, which is located in the outlet 32 of the material passage 3, and any cross section of the end in the direction perpendicular to the outlet 32 can be regarded as an adjusting portion, i.e. the conical end of the pin 61 can be regarded as an infinite number of adjusting portions arranged in sequence. The spraying amount of the material in a unit time under the same air flow rate can be adjusted by controlling the adjusting parts with different section sizes to be positioned in the outlet 32, so that the material amount of a target spraying area is controlled. So, under the unchangeable condition of air flow rate, can change the outflow of material, and then the regional material thickness of control target spraying.

In this embodiment, the position of the pin 61 is controlled by rotating the adjusting nut 6; in other embodiments, the position of the pin may also be adjusted by pressing or the like.

In this embodiment, the largest cross-sectional dimension of the pins 61 in a direction perpendicular to the outlet of the material passageway 3 is larger than the cross-sectional dimension of the outlet 32 of the material passageway 3. So, can realize the shutoff of the export 32 of material route 3 through the position of adjusting contact pin 61 to avoid material to spill in the material route 3, improve the performance of air brushing device.
