Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, specifically a spray painting equipment used in building construction. Background Technology

[0002] In construction, a spray painting device is a tool or equipment used to quickly and evenly apply coatings (such as paint, anti-corrosion coatings, fire-retardant coatings, etc.). It is widely used in painting operations on surfaces such as walls, ceilings, steel structures, and pipes, and can significantly improve construction efficiency and reduce labor costs. Conventional spray painting devices deliver compressed air into the paint can and then spray it through nozzles. However, the air compressor is directly connected to the paint can, and the compressed air delivered by the compressor is unstable, which can lead to uneven paint coverage. Utility Model Content

[0003] The purpose of this invention is to provide a painting device for building construction to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a spray painting device for building construction, characterized in that it includes;

[0005] The spray can is equipped with a pressure control structure, which includes a sealing cap, a pressurizing tank, a spray pipe, a pressure tank, and a control valve.

[0006] The sealing cap is fastened to the top of the spray can and threadedly connected to it. The top of the sealing cap is fixed integrally with the pressurized tank, and the bottom of the pressurized tank has multiple air inlets. An air inlet connector is installed on the outside of the pressurized tank. The bottom of the spray pipe passes through the pressurized tank and the sealing cap and is embedded inside the spray can.

[0007] The control valve is installed on the top of the pressure tank, and the pressure tank has an air inlet pipe on its side.

[0008] Preferably, the inner side of the pressure tank is concave, and the outer side of the spray can is fitted into the pressure tank. By embedding the spray can into the pressure tank, the structure becomes more compact, making better use of space and improving the portability of the product.

[0009] Preferably, the pressure tank has an exhaust valve installed on the outside and a pressure sensor inside. The air inside the pressure tank is connected to the air inside the spray can. The pressure sensor monitors the internal pressure of the pressure tank in real time. When the internal pressure of the pressure tank is too high, the exhaust valve is used to exhaust the air, so that the air pressure is balanced and the sprayed pigment is uniform.

[0010] Preferably, the pipe at the top of the pressure tank is connected to the air inlet connector and fixed by a nut, so that the pipe on the control valve is connected to the air inlet connector as one unit. The pressure tank stores compressed air, and then the compressed air is delivered to the inside of the booster tank by the control valve, thereby regulating the internal pressure of the booster tank.

[0011] Preferably, the end of the air inlet pipe furthest from the pressure tank is connected to an air compressor, which delivers compressed air to the inside of the pressure tank, thereby achieving the function of storing compressed air.

[0012] Preferably, the pressure tank has a fixing frame at the bottom, and one end of the fixing frame has an integrally fixed limiting plate. The limiting plate is attached to the outside of the spray can. The outside of the pressure tank has an integrally fixed limiting block. The end of the fixing frame away from the limiting plate has a fixing bolt. The fixing bolt passes through the fixing frame and abuts against the limiting block, thereby causing the limiting plate to tighten the spray can, so that the spray can is tightly embedded in the pressure tank. The spray can can be replaced to spray different materials, and the internal pressure of the pressurized tank can be adjusted to be used for spraying different materials.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Compressed air is supplied to the pressure tank by an air compressor, and the pressure tank serves as a compressed air storage tank. The compressed air is then controlled by a control valve to supply compressed air to the booster tank, thereby regulating the internal pressure of the booster tank. The booster tank is equipped with a pressure sensor, and the air inside the booster tank is connected to the air inside the spray can. The pressure sensor monitors the internal pressure of the booster tank in real time. When the internal pressure of the booster tank is too high, the air is released through the exhaust valve to balance the air pressure and make the sprayed pigment uniform.

[0015] 2. The spray tank can be replaced to spray different materials, and the internal pressure of the pressurized tank can be adjusted to be used for spraying different materials. Attached Figure Description

[0023] Please see Figure 1-3 This utility model provides a technical solution: a spray painting device for building construction, comprising;

[0024] The spray can 100 is equipped with a pressure control structure, which includes a sealing cover 200, a pressurizing tank 201, a spray pipe 203, a pressure tank 300, and a control valve 301.

[0025] The sealing cap 200 is fastened to the top of the spray can 100 and threadedly connected thereto. The top of the sealing cap 200 is integrally fixed with the pressurizing tank 201. The bottom of the pressurizing tank 201 is provided with multiple air inlets 205. An air inlet connector 204 is installed on the outside of the pressurizing tank 201. The bottom of the spray pipe 203 passes through the pressurizing tank 201 and the sealing cap 200 and is embedded inside the spray can 100.

[0026] The control valve 301 is installed on the top of the pressure tank 300, and the side of the pressure tank 300 has an air inlet pipe 303.

[0027] Furthermore, the inner side of the pressure tank 300 is concave, and the outer side of the spray can 100 is fitted into the pressure tank 300. By embedding the spray can 100 into the pressure tank 300, the structure becomes more compact, making better use of space and improving the portability of the product.

[0028] Furthermore, the pressure tank 201 has an exhaust valve 202 installed on its outer side, and a pressure sensor is installed inside the pressure tank 201. The air inside the pressure tank 201 is connected to the air inside the spray can 100. The pressure sensor monitors the internal pressure of the pressure tank 201 in real time. When the internal pressure of the pressure tank 201 is too high, the exhaust valve 202 is used to exhaust the air, so that the air pressure is balanced and the sprayed pigment is uniform.

[0029] Furthermore, the pipe at the top of the pressure tank 300 is connected to the air inlet connector 204 and fixed by a nut, so that the pipe on the control valve 301 is connected to the air inlet connector 204 as one unit. The pressure tank 300 stores compressed air, and then the compressed air is delivered to the inside of the booster tank 201 by the control valve 301, thereby regulating the internal pressure of the booster tank 201.

[0030] Furthermore, an air compressor is connected to the end of the air intake pipe 303 that is away from the pressure tank 300. The air compressor delivers compressed air to the inside of the pressure tank 300, and the pressure tank 300 serves as a storage device for compressed air.

[0031] Furthermore, the bottom of the pressure tank 300 has a fixing frame 400, one end of which has an integrally fixed limiting plate 401. The limiting plate 401 is attached to the outside of the spray can 100. The outside of the pressure tank 300 has an integrally fixed limiting block 302. The end of the fixing frame 400 away from the limiting plate 401 has a fixing bolt 402. The fixing bolt 402 passes through the fixing frame 400 and abuts against the limiting block 302, thereby causing the limiting plate 401 to tighten the spray can 100, so that the spray can 100 is tightly embedded in the pressure tank 300. The spray can 100 can be replaced to spray different materials, and the internal pressure of the pressurized tank 201 can be adjusted to spray different materials.

[0032] Working principle: In use, the material to be sprayed is loaded into the spray can 100, and then sealed by fastening the top of the spray can 100 with the sealing cap 200. Next, the fixing bracket 400 is attached to the bottom of the spray can 100 and the pressure tank 300. Rotating the fixing bolt 402 tightens the spray can 100 via the limiting plate 401, thus fixing the spray can 100 and the pressure tank 300 in place. Then, compressed air is supplied to the pressure tank 300 via an air compressor, achieving the function of compressed air storage in the pressure tank 300. The pressure tank 300 stores compressed air, which is then controlled by the control valve 301 to be delivered to the pressure tank 201, thereby regulating the internal pressure of the pressure tank 201. The pressure tank 201 is equipped with a pressure sensor, and the air inside the pressure tank 201 is connected to the air inside the spray can 100. The pressure sensor monitors the internal pressure of the pressure tank 201 in real time. When the internal pressure of the pressure tank 201 is too high, the air is exhausted through the exhaust valve 202 to balance the air pressure and make the sprayed pigment uniform.

[0033] Furthermore, the spray can 100 can be replaced to spray different materials, and the internal pressure of the pressurized tank 201 can be adjusted to spray different materials.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
