[0002] Buildings are exposed to wind, sunlight, rain, wear, corrosion, etc. for a long time, and the surface of building decoration will be damaged. In order to protect buildings from the influence and damage of the environment, it is necessary to spray paint on the surface of buildings. Paint can not only protect the surface of the coated object, prevent erosion from light, oxygen, chemical substances, solvents, etc. from the outside, improve the service life of the coated object, but also coat the surface of the substance, change its color, pattern, luster, texture, etc., and improve the aesthetic value of the building. However, in current building construction, the commonly used method is to manually spray using a wall spraying device. Sometimes, the paint contains impurities and is prone to clogging the nozzle.

[0003] In the prior art, the wall spraying device does not have a cleaning function. It is necessary to disassemble the spraying device to clean the inside, which affects work efficiency. Moreover, the particles of the sprayed paint are relatively large, affecting the spraying effect. Summary of the Utility Model

[0004] The purpose of the utility model is to address the above-mentioned existing technical problems and provide a wall decoration spraying device. When spraying, the paint in the first diversion channel collides with the high-pressure gas in the spiral-shaped second diversion channel. The high-pressure gas in the second diversion channel forms a vortex at the paint spraying hole, causing the paint to form several paint particles and be sprayed out, improving the spraying effect. An end cap is provided on the paint spraying hole, and water or cleaning liquid is introduced into the second pipe body, enabling the water or cleaning liquid to flow reversely into the second diversion channel from the paint spraying hole, cleaning the second diversion channel and discharging impurities, and discharging them along the first pipe body.

[0005] In view of this, the utility model provides a wall decoration spraying device, including:

[0006] A housing, with a paint spraying hole provided at one end of the housing;

[0007] A plug, arranged inside the housing. The plug includes a base and a conical deflector near one end of the paint spraying hole.

A ring groove is provided on the connecting portion, and an annular cavity is formed between the ring groove and the inner peripheral wall of the housing. A first diversion channel is penetrated through the plug, and the first diversion channel communicates with the paint spraying hole;

[0008] A first pipe body, arranged on the housing and communicating with the first diversion channel;

[0009] A second pipe body, arranged on the housing and communicating with the annular cavity;

[0010] Among them, a plurality of flow guiding grooves are formed in the outer peripheral wall of the conical flow guide body, and the flow guiding grooves are spiral. A second flow guiding channel is formed between the flow guiding grooves and the inner peripheral wall of the shell. The annular cavity, the second flow guiding channel and the material spraying holes are communicated in sequence. An end cover is detachably arranged on the material spraying holes.

[0011] In the above solution, further, a filtering member is arranged in the shell, and the filtering member is located at one end of the first flow guiding channel close to the first pipe body. The filtering member includes:

[0012] A support ring arranged in the shell;

[0013] A filter net arranged in the support ring.

[0014] In the above solution, further, both sides of the support ring are axially abutted against the base and the first pipe body respectively.

[0015] In the above solution, further, the material spraying holes include:

[0016] A first cavity located at one end of the shell close to the conical flow guide body;

[0017] A second cavity located at one end of the first cavity far from the conical flow guide body, and the second cavity is communicated with the first cavity;

[0018] Among them, a discharge hole is arranged at one end of the first flow guiding channel close to the first cavity. The inner diameter of the discharge hole is smaller than the inner diameter of the first cavity.

[0019] In the above solution, further, a sealing ring is arranged between the base and the shell.

[0020] In the above solution, further, the end cover is threadedly connected to the material spraying hole.

[0021] The beneficial effects of the utility model are as follows:

[0022] 1. During spraying, the paint in the first flow guiding channel collides with the high-pressure gas in the spiral second flow guiding channel. The high-pressure gas in the second flow guiding channel forms a vortex at the material spraying hole, causing the paint to form several paint particles and be ejected, improving the spraying effect. An end cover is arranged on the material spraying hole, and water or cleaning liquid is introduced into the second pipe body, enabling the water or cleaning liquid to flow reversely into the second flow guiding channel from the material spraying hole, cleaning the second flow guiding channel and discharging impurities, and discharging along the first pipe body;

In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] Embodiment 1:

[0035] This embodiment provides a wall decoration spraying device, including:

[0036] A housing 1, one end of the housing 1 is provided with a material spraying hole 8;

[0037] A plug-in 2, disposed inside the housing 1. The plug-in 2 includes a base 21 and a conical deflector 22 near one end of the material spraying hole 8. The base 21 and the conical deflector 22 are connected through a connecting portion 23. A ring groove 5 is provided on the connecting portion 23. An annular cavity 6 is formed between the ring groove 5 and the inner peripheral wall of the housing 1. A first diversion channel 7 is provided through the plug-in 2, and the first diversion channel 7 communicates with the material spraying hole 8;

[0038] A first pipe body 3, disposed on the housing 1 and communicating with the first diversion channel 7;

[0039] A second pipe body 4, disposed on the housing 1 and communicating with the annular cavity 6;

[0040] Wherein, a plurality of diversion grooves 9 are formed on the outer peripheral wall of the conical deflector 22, and the diversion grooves 9 are spiral. A second diversion channel 10 is formed between the diversion grooves 9 and the inner peripheral wall of the housing 1. The annular cavity 6, the second diversion channel 10, and the material spraying hole 8 are sequentially communicated. An end cover 12 is detachably provided on the material spraying hole 8.

[0041] In this technical solution, a conical cavity close to the material spraying hole 8 and a plurality of cylindrical cavities communicating with the conical cavity are provided inside the housing 1. The plug-in 2 is inserted from one end of the housing 1 away from the material spraying hole 8, so that the conical deflector 22 abuts against the surface of the conical cavity, and the cylindrical cavity abuts against the outer peripheral wall of the base 21.

[0042] The first diversion channel 7 may include a cylindrical hole provided in the base 21 and the connecting portion 23 and a conical hole provided in the conical deflector 22.

[0043] The first pipe body 3 is used to provide liquid paint. A pump body can be arranged on the first pipe body 3 to suck in the paint. The paint sequentially passes through the first pipe body 3, the first diversion channel 7, and the material spraying hole 8. The first pipe body 3 can be threadedly connected to the housing 1, which is convenient for installation and disassembly.

[0044] The second pipe body 4 is used to provide high-pressure air. A pump body can be arranged on the second pipe body 4 to suck in the air. The high-pressure gas sequentially passes through the second pipe body 4, the annular cavity 6, the second diversion channel 10, and the material spraying hole 8. The second pipe body 4 can be integrally formed with the outer shell or can be threadedly connected to the housing 1, which is convenient for installation and disassembly.

[0045] The fluid pressure of the second pipe body 4 can be greater than the fluid pressure of the first pipe body 3. The fluid of the high-pressure second pipe body 4 can split the fluid of the first pipe body 3 into small particles, so that the fluid of the first pipe body 3 can be finely sprayed. In addition, when the fluid of the second pipe body 4 is sprayed from the material spraying hole 8, the fluid of the first pipe body 3 can flow due to the pressure difference. Therefore, the fluid of the first pipe body 3 can move to the material spraying hole 8 due to the pressure difference.

[0046] The conical deflector 22 is conical. A plurality of diversion grooves 9 are formed on the outer peripheral wall of the conical deflector 22, and the diversion grooves 9 are spiral. The formed second diversion channel 10 is spiral. The high-pressure gas in the second pipe body 4 rotates at a high speed along the spiral second diversion channel 10. Through the rotating action, the high-pressure gas forms a vortex, causing the air to collide with the paint, thereby colliding the paint into several particles. The paint particles and the air are sprayed from the material spraying hole 8 to form a paint spray. Setting the spiral second diversion channel 10 can reduce the diameter of the paint particles, so that the paint spray is ejected finer and the effect of the paint spraying on the wall is improved.

[0047] When spraying the wall, remove the end cover 12. Paint is introduced into the first pipe body 3, and at the same time, high-pressure gas is introduced into the second pipe body 4. The paint passes through the first diversion channel 7 and enters the material spraying hole 8. At the same time, the high-pressure gas enters the annular cavity and enters the material spraying hole 8 along the plurality of spiral second diversion channels 10. At this time, the high-pressure gas forming a vortex collides with the paint to form several fine particles, and then is ejected onto the wall.

[0048] The end cover 12 is detachably arranged on the material spraying hole 8. The end cover 12 can be snap-connected or threadedly connected to the material spraying hole 8. The end cover 12 is used to block the material spraying hole 8. Since the outlet of the first diversion channel 7 is small, when the outlet of the first diversion channel 7 is blocked by impurities or when it is necessary to clean the inside of the first diversion channel 7 after use, the end cover 12 can be covered on the material spraying hole 8.

[0049] After the end cap 12 covers the spraying hole 8, water or other liquid capable of cleaning the first diversion channel 7 is introduced into the second tube body 4, no liquid or gas is introduced into the first tube body 3, and the pump body is closed. The liquid enters the annular cavity and enters the spraying hole 8 along a plurality of spiral second diversion channels 10. The diameter of the spraying hole 8 is larger than the outlet of the first diversion channel 7. After the liquid impacts the end cap 12, it reversely enters the first diversion channel 7, flushing and washing the inside of the first diversion channel 7 and washing away the blocked foreign matters, and finally discharging from the first tube body 3.

[0050] Embodiment 2:

[0051] This embodiment provides a wall decoration spraying device. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0052] A filter element 11 is arranged in the housing 1. The filter element 11 is located at one end of the first diversion channel 7 close to the first tube body 3. The filter element 11 includes:

[0053] A support ring 111, arranged in the housing 1;

[0054] A filter net 112, arranged in the support ring 111.

[0055] In this technical solution, the filter element 11 can be clamped or fixed in the housing 1 with screws. The filter element 11 can also be installed at the end of the base 21. The filter element 11 is used to filter the paint in the first tube body 3. The filtered paint can enter the first diversion channel 7, and the filtered impurities remain on one side of the filter net 112 close to the first tube body 3. The filter element 11 can prevent foreign matters from blocking the outlet of the first diversion channel 7.

[0056] Therefore, when cleaning the inside of the first diversion channel 7 or removing the foreign matters blocking the outlet of the first diversion channel 7, when the cleaning liquid reversely enters the first diversion channel 7, the liquid can wash down the impurities remaining on one side of the filter net 112 close to the first tube body 3 and flow out along the first tube body 3, without removing the filter element 11 for cleaning and replacement.

[0057] The filter net 112 can be a metal filter net 112, and the support ring 111 abuts against the inner peripheral wall of the housing 1.

[0058] Further, both sides of the support ring 111 axially abut against the base 21 and the first tube body 3 respectively.

[0059] In this technical solution, the abutting method plays a role in facilitating installation and disassembly. When it is necessary to take out the filter element 11, directly taking out the first tube body 3 can directly take out the filter element 11.

[0060] Embodiment 4:

[0061] This embodiment provides a wall decoration spraying device, which, in addition to the technical solutions of the above embodiment, further has the following technical features.

[0062] The material spraying hole 8 includes:

[0063] A first cavity 81, located at one end of the housing 1 close to the conical deflector 22;

[0064] A second cavity 82, located at one end of the first cavity 81 away from the conical deflector 22, and the second cavity 82 communicates with the first cavity 81;

[0065] Wherein, a discharge hole 13 is provided at one end of the first diversion channel 7 close to the first cavity 81. The inner diameter of the discharge hole 13 is smaller than the inner diameter of the first cavity 81. The inner diameter of the first cavity 81 is larger than the inner diameter of the second cavity 82, and the volume of the second cavity 82 is smaller than the volume of the first cavity 81.

[0066] In this technical solution, the discharge hole 13 is located at the outlet of the first diversion channel 7. The first cavity 81 can provide a predetermined space for the high-pressure gas flowing out of the second pipe body 4 and turning into a vortex, guide the paint in the first pipe body 3 to move forward, and make the paint particles smaller.

[0067] Since the volume of the second cavity 82 is smaller than the volume of the first cavity 81, the inner diameter of the discharge hole 13 is smaller than the inner diameter of the first cavity 81, the inner diameter of the first cavity 81 is larger than the inner diameter of the second cavity 82, and the inner diameter of the discharge hole 13 can be smaller than the inner diameter of the second cavity 82. The paint discharged from the discharge hole 13 sequentially passes through the first cavity 81 and the second cavity 82, which can further reduce the diameter of the paint particles and improve the spraying effect.

[0068] Embodiment 5:

[0069] This embodiment provides a wall decoration spraying device, which, in addition to the technical solutions of the above embodiment, further has the following technical features.

[0070] A sealing ring 14 is provided between the base 21 and the housing 1.

[0071] In this technical solution, the sealing ring 14 can be a conventional elastic sealing ring 14. The sealing ring 14 is used to seal between the base 21 and the housing 1 to prevent the liquid in the first pipe body 3 from entering the annular cavity.

[0072] Embodiment 6:

[0073] This embodiment provides a wall decoration spraying device, which, in addition to the technical solutions of the above embodiment, further has the following technical features.

[0074] The end cover 12 is threadedly connected to the material spraying hole 8.

[0075] In this technical solution, the threaded connection method facilitates the installation and disassembly of the end cover 12 and has better stability.
