Detailed implementation manners

[0020] In order to further explain the technical solution of the present invention, the following will be elaborated in detail through specific embodiments.

[0021] Please refer to Figure 1 , the present invention provides a spraying device for lightweight building materials, including a handle 1, a trigger switch 2, a feed pipe 3, a spray pipe 4, an atomizing nozzle 5 and an auxiliary spraying device 6. A trigger switch 2 is arranged at the bottom of the handle 1, a feed pipe 3 is connected to the rear of the handle 1, a spray pipe 4 is connected to the front of the handle 1, an atomizing nozzle 5 is installed at the front end of the spray pipe 4, and an auxiliary spraying device 6 is arranged on the surface of the spray pipe 4.

[0022] Please refer to Figure 2 , the present invention provides a spraying device for lightweight building materials. The auxiliary spraying device 6 includes a movable sleeve 61, a bracket 62 and a support roller 63. The movable sleeve 61 is movably sleeved on the surface of the spray pipe 4. A bracket 62 is connected to the bottom of the movable sleeve 61. A support roller 63 is rotatably installed at the inner bottom of the bracket 62. The support roller 63 can be attached to the wall surface to provide support for the spray pipe 4, making it more labor-saving for the user to control the spray pipe 4 for spraying. Moreover, the spray pipe 4 can move straight back and forth along the wall surface through the support roller 63, with strong controllability, ensuring the spraying uniformity.

[0023] Further explanation, the support roller 63 adopts a putty roller, so that the support roller 63 can not only play a supporting role, but also brush and level the putty sprayed on the wall surface, with multiple functions.

[0024] Further explanation, the length of the support roller 63 is not less than 25 cm, so that the support roller 63 has a large enough contact range with the wall surface, and can better brush and level the putty sprayed on the wall surface.

[0025] Please refer to Figure 3 , the present invention provides a spraying device for lightweight building materials. An insertion slot 64 is opened at the lower part of the front side of the movable sleeve 61. A mounting plate 65 is integrally arranged at the top end of the bracket 62. The mounting plate 65 is inserted into the inner side of the insertion slot 64. A positioning bolt 66 is threadedly connected to the screw hole at the bottom of the insertion slot 64. The positioning bolt 66 longitudinally passes through the insertion slot 64 and the mounting plate 65 and is threadedly connected thereto, thereby realizing the installation connection between the bracket 62 and the movable sleeve 61, making the bracket 62 and the movable sleeve 61 easy to disassemble and assemble, and facilitating the disassembly, washing and replacement of the support roller 63.

[0026] Please refer toFigure 4 , the present utility model provides a spraying device for lightweight building materials. The rear end of the movable sleeve 61 is fixedly connected to the adjusting sleeve 67 through a connecting frame. The adjusting sleeve 67 is movably sleeved on the surface of the spray pipe 4. An installation hole 68 is provided through the side wall surface of the adjusting sleeve 67. A handle 69 is provided on the side of the adjusting sleeve 67. A threaded head 610 is provided at the head of the handle 69. The handle 69 is threadedly connected to the installation hole 68 through the threaded head 610. The head of the threaded head 610 can pass through the installation hole 68 and abut against the surface of the spray pipe 4 to fix the position of the adjusting sleeve 67.

[0027] Furthermore, two installation holes 68 are provided. The two installation holes 68 are symmetrically arranged on the left and right sides of the adjusting sleeve 67, so that the handle 69 can be installed in two directions on the left and right of the adjusting sleeve 67, which can better suit the user groups with different operating habits.

[0028] The working principle is as follows:

[0029] First, during use, first connect the feeding pipe 3 to an external booster pump. Then hold the machine handle 1 with one hand and hold the handle 69 with the other hand to stably hold the spray pipe 4, improving the controllability of the spray pipe 4. Subsequently, aim the atomizing nozzle 5 at the wall and press the trigger switch 2. The spray pipe 4 can atomize and spray the putty onto the wall through the atomizing nozzle 5, thus realizing the spraying construction of the putty.

[0030] Second, during the use process, the spray pipe 4 can be supported on the wall through the supporting roller 63 at its bottom, making it more labor-saving for the user to control the spray pipe 4 for spraying. And the spray pipe 4 can move straight back and forth along the wall through the supporting roller 63, with strong controllability, ensuring the spraying uniformity. In addition, when the supporting roller 63 moves, it can also brush and level the putty sprayed on the wall, ensuring the putty application quality.

[0031] Third, during the use process, the user can adjust the position of the supporting roller 63 according to his own operating habit. The specific operation is as follows: First, loosen the handle 69 so that the threaded head 610 retracts from the surface of the spray pipe 4 and returns to the inside of the installation hole 68. At this time, the adjusting sleeve 67 resumes free movement. Then, the position of the supporting roller 63 can be adjusted by pushing the movable sleeve 61 to move through the adjusting sleeve 67. After the supporting roller 63 reaches the preset position, tighten the handle 69 so that the threaded head 610 abuts against the surface of the spray pipe 4, fixing the adjusting sleeve 67 on the surface of the spray pipe 4, and the movable sleeve 61 is also fixed together with the adjusting sleeve 67, thus completing the adjustment of the position of the supporting roller 63. The position of the supporting roller 63 can be adjusted according to the user's usage habit, with strong applicability.

[0032] Fourth, after use, screw out the positioning bolt 66 from the bottom of the insertion slot 64, and then pull out the mounting piece 65 from the inside of the insertion slot 64, then the bracket 62 can be disassembled and removed from the movable sleeve 61, which is convenient for disassembling, washing and replacing the supporting roller 63.

[0033] The above are only the preferred examples of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
