[0002] An airless sprayer utilizes a high-pressure plunger pump to pressurize the paint, delivering it to a spray gun via a high-pressure hose. The nozzle then releases the pressure to create an atomized coating. This type of equipment is primarily used to create a dense coating on wall surfaces and is widely used in various spray painting projects. Compared to traditional air spray, this spraying method offers advantages such as a uniform finish, a grain-free finish, and a fast drying time. It is particularly suitable for the application of high-viscosity paints and can create clear boundaries, even in spraying projects with demanding boundaries.

Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-5As shown, an airless sprayer support structure includes an upper support 1, one end of the upper support 1 is fixedly connected to a water tank support 3 and a drive motor 4, one end of the water tank support 3 is fixedly connected to a water tank 6, and paint for spraying is stored in the water tank 6, a bottom support 2 is fixedly connected below the upper support 1, one end of the drive motor 4 is fixedly connected to a pump body 5, one end of the pump body 5 is fixedly connected to a filter component 7, the other end of the pump body 5 is fixedly connected to a spray handle 8 through a pipe, and one end of the spray handle 8 is fixedly connected to a duckbill seat 9;

[0031] The upper bracket 1 and the bottom bracket 2 are preferably welded from square steel. During installation, the drive motor 4 is installed vertically, and the pump body 5 is placed horizontally on the lower side of the drive motor 4. The water tank 6 is installed on the other side by a water tank bracket 3 made by bending the steel plate. This can greatly save the installation space of the device, make it easy to move and carry, and improve the stability during use. A filter material is installed in the spray handle 8 to filter the sprayed paint to prevent clogging during painting. The duckbill seat 9 ensures that the paint can be sprayed smoothly and can prevent dripping. At the same time, it fixes the nozzle and ensures its sealing, thereby preventing paint leakage during the painting process.

[0032] In this embodiment, a filter component 7 is fixedly connected to one end of the pump body 5, and a filter plate 11 is fixedly connected to the inside of the water tank 6. The filter component 7 can filter the paint pumped out of the pump body 5, and cooperate with the filter plate 11 installed at the front end of the outlet below the water tank 6 to filter the paint in multiple steps and stages to prevent the nozzle from being blocked during jetting.

[0033] Example 2:

[0034] An airless sprayer support structure, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1-5 As shown,

[0035] In this embodiment, one end of the water tank 6 is fixedly connected to a fixing plate 12, and the fixing plate 12 can be fixed to the water tank 6 from one side by bolts to prevent shaking during stirring. The lifting bracket 16 and one end of the pump body 5 are fixedly connected to the lower end joint 13, and one end of the lower end joint 13 is provided with a valve that can be used to close the lower end of the water tank 6. One end of the upper bracket 1 is slidably connected to a stabilizing rod 23, and one end of the stabilizing rod 23 is fixedly connected to the lifting bracket 16. One end of the lifting bracket 16 is fixedly connected to an electric screw 22, and the movable end of the electric screw 22 is threadedly connected to the upper bracket 1;

[0036] One end of the lifting bracket 16 is rotatably connected to the rotating bracket 15, and one end of the rotating bracket 15 is fixedly connected to the stirring motor 14. The power output end of the stirring motor 14 is fixedly connected to the cross boss 21;

[0037] A cover plate 10 is fixedly connected above the water tank 6, a bearing 19 is fixedly connected to one end of the cover plate 10, a stirring shaft 18 is fixedly connected to the movable end of the bearing 19, the slot of the cross boss 21 corresponds to the cross slot above the stirring shaft 18, a docking joint 20 is provided above the stirring shaft 18, and a plurality of stirring paddles 24 are fixedly connected below the stirring shaft 18.

[0038] In this embodiment, when the device is used for a long time, in order to prevent the paint stored in the water tank 6 from stratifying and settling, it needs to be stirred. At the same time, when different colors or different types of pigments need to be used in some spraying operations, the water tank 6 needs to be replaced. However, it will be very troublesome to clean the parts used for stirring the water tank 6 at this time. Therefore, when replacing the water tank 6, the electric screw 22 is started to raise the lifting bracket 16, and then the stirring motor 14 is rotated to make the cross boss 21 at one end of the stirring motor 14 align with the cross slot above the stirring shaft 18 below, and then the electric screw 22 is turned over to make the cross boss 21 inserted into the stirring shaft 18 to drive the stirring shaft 18 to rotate and drive the multiple stirring paddles 24 to stir;

[0039] When replacement is needed, you only need to lift the stirring motor 14 again to disengage the cross boss 21 from the stirring shaft 18, then pull out the water tank 6 from one side of the water tank bracket 3. After replacing the water tank 6 to store other paints, you can quickly connect it to the stirring shaft 18 for stirring. No additional cleaning steps are required, which can effectively prevent dust from entering and contaminating the paint due to opening the cover 10.

[0040] In this embodiment, a plurality of pressure plates 25 are rotatably connected inside the water tank 6 , and a positioning pin 26 is slidably connected to one end of the pressure plate 25 . The positioning pin 26 can fix the pressure plate 25 to prevent the filter 11 from being lost in the water when cleaning the water tank 6 .

[0041] In this embodiment, one end of the upper bracket 1 is fixedly connected to a heating component 17, and one end of the heating component 17 is fixedly connected to the water tank 6. The heating component 17 is preferably a heating blanket, which can heat the water tank 6 externally.

[0042] In this embodiment: when the device is used for a long time, in order to prevent the paint stored in the water tank 6 from stratifying and settling, it needs to be stirred. At the same time, when different colors or different types of pigments need to be used in some spraying operations, the water tank 6 needs to be replaced. However, it will be very troublesome to clean the parts used for stirring the water tank 6 at this time. Therefore, when replacing the water tank 6, the electric screw 22 is started to raise the lifting bracket 16, and then the stirring motor 14 is rotated to make the cross boss 21 at one end of the stirring motor 14 align with the cross slot above the stirring shaft 18 below, and then the electric screw 22 is turned over to make the cross boss 21 inserted into the stirring shaft 18 to drive the stirring shaft 18 to rotate and drive the multiple stirring paddles 24 to stir;

[0043] When it is necessary to replace the paint, it is only necessary to lift the stirring motor 14 again to disengage the cross boss 21 from the stirring shaft 18, and then pull out the water tank 6 from the side of the water tank bracket 3. After replacing the water tank 6 storing other paints, it can be quickly docked with the stirring shaft 18 for stirring, without the need for additional cleaning steps, which can effectively prevent dust from entering and contaminating the paint due to opening the cover 10;

[0044] The positioning pin 26 can fix the pressure plate 25 to prevent the filter 11 from being lost in the water when cleaning the water tank 6. The heating component 17 is preferably a heating blanket, which can heat the water tank 6 externally.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
