Description

Technical Field

[0001] The utility model relates to the field of building decoration engineering, in particular to an appliance used for building decoration engineering, specifically a handheld wall painting device. Background Art

[0002] Wall decoration includes painting, and a general construction method is to use a paint roller to paint the wall. Since the paint roller can absorb less paint, the paint roller needs to be dipped in paint frequently, and the efficiency of the painting construction is not high.

[0003] The patent application publication number CN 114250953 A discloses a wall painting device for construction and its use method. The painting liquid is first placed in a box, and then the painting liquid in the box is pumped into the painting mechanism through a pump and a water pipe, and then the wall is directly painted through the painting mechanism. This method avoids the problem of constantly dipping paint during painting, and also avoids ground pollution caused by paint falling, as well as the problem of paint waste. However, this method requires an electric pump and is suitable for sites with power supply conditions. In addition, the pump and the water pipe pump the painting liquid to the painting roller, and the painting liquid is unevenly distributed on the roller surface of the painting roller. For the same part of the wall, it is often necessary to paint multiple times to ensure that the painting liquid is evenly distributed, which reduces the efficiency of the painting construction.

[0021] The utility model will be further described below in conjunction with the accompanying drawings.

[0022] See also Figures 1 to 4 The handheld wall painting device of the utility model comprises a box body 1, and the box body 1 has an open paint cavity. The box body 1 can be a whole, or it can be assembled from two or more parts. For example, in Figure 1 In the illustrated embodiment, the box body 1 includes a box body 1-1 and a box cover 1-2, and the box cover 1-2 is fixedly mounted on the box body 1-1 by at least two bolts 10. The box cover 1-2 is preferably in the shape of a plate, and the paint cavity can be fully exposed by opening the box cover 1-2, so that it is convenient for assembling the handheld wall painting device and cleaning the paint cavity. In order to ensure the airtightness between the box body 1-1 and the box cover 1-2, that is, to ensure the airtightness of the paint cavity, a sealing strip 11 is provided between the box body 1-1 and the box cover 1-2. In order to facilitate the installation of the sealing strip, at least one of the box body 1-1 and the box cover 1-2 is provided with a sealing groove, and the sealing strip 11 is located in the sealing groove. For example, in Figure 1 In the illustrated embodiment, a sealing groove is provided at the position where the box body 1-1 and the box cover 1-2 contact each other, and a sealing strip 11 is fixed at the position where the box cover 1-2 and the box body 1-1 contact each other. The paint chamber is used to store paint, which includes slurry such as paint and pigment applied to the wall. The paint chamber is open mainly for painting construction, and also for adding paint to the paint chamber. For example, see Figure 1 The box body 1 has a generally rectangular shape, and a top plate and a side plate of the box body 1 are provided with notches to form a rectangular open paint cavity.

[0023] The box body 1 is fixedly mounted with a first support rod 2 and a second support rod 3, the first support rod 2 and the second support rod 3 are parallel to each other, the first support rod 2 is located outside the paint cavity, and the second support rod 3 is located inside the paint cavity. The first support rod 2 and the second support rod 3 can be fixed to the box body 1-1, or fixed between the box body 1-1 and the box cover 1-2. In order to simplify the structure of the box body 1 and improve the strength of the box body 1, and also to facilitate the fixing of the first support rod 2 and the second support rod 3, one end of the first support rod 2 is fixedly mounted on the box body 1-1, and the end surface of the other end is provided with a threaded hole, and the bolt 10 passes through the box cover 1-2 and is connected to the threaded hole of the first support rod 2; one end of the second support rod 3 is fixedly mounted on the box body 1-1, and the end surface of the other end is provided with a threaded hole, and the bolt 10 passes through the box cover 1-2 and is connected to the threaded hole of the second support rod 3.

[0024] The first support rod 2 is provided with a first rotating body 4 that can rotate around the first support rod 2, and the second support rod 3 is provided with a second rotating body 5 that can rotate around the second support rod 3. The first rotating body 4 and the second rotating body 5 are connected by a synchronous belt 6, and the synchronous belt 6 is annular. A brushing cloth is fixed on the outer surface of the synchronous belt 6. The first rotating body 4 and the second rotating body play the role of increasing the distance between the annular synchronous belt 6, and also play the role of reducing the resistance of the synchronous belt 6 to rotation. For example, the first rotating body 4 is a bearing or a roller, and the second rotating body 5 is a bearing or a roller. The diameters of the first support rod 2 and the second support rod 3 are not large. If the synchronous belt 6 is directly connected to the first support rod 2 and the second support rod 3, the annular synchronous belt 6 will contact and adhere to each other at will, affecting the rotation of the synchronous belt 6. The paint cloth is used to absorb paint and apply the paint to the wall. The paint cloth can be made of wool.

[0025] In order for the synchronous belt 6 and the coating cloth to fully absorb the paint, the first support rod 2 and the second support rod 3 are preferably located at diagonal positions of the box body 1. Figure 1 In the orientation shown, the overall shape of the box body 1 is a rectangular parallelepiped, the top plate and the right side plate of the box body 1 are provided with notches to form a rectangular parallelepiped paint cavity, and the first support rod 2 and the second support rod 3 are respectively located at the upper right corner and the lower left corner of the box body 1.

[0026] In order to prevent the painting cloth from absorbing too much paint, the box body 1 is also provided with a scraper plate 7, and the edge of the scraper plate 7 is in clearance with the painting cloth. The paint scraped off from the painting cloth by the scraper plate 7 falls into the paint cavity, so the scraper plate 7 is located at the first support rod 2. After the painting cloth absorbs the paint in the paint cavity, it first passes through the scraper plate 7 along the rotation direction of the synchronous belt 6 and then contacts the wall surface, so the scraper plate 7 is located upstream of the first support rod 2. In order to control the painting cloth to absorb only an appropriate amount of paint when it contacts the wall surface, the distance between the edge of the scraper plate 7 and the painting cloth is generally 0.2 to 0.4 cm.

[0027] The paint is loaded into the paint chamber, a part of the synchronous belt 6 and the painting cloth are immersed in the paint, and the box body 1 is held to make the painting cloth contact the wall. Since there is a large friction coefficient between the painting cloth and the wall, the box body 1 is moved under the premise of keeping the painting cloth in contact with the wall, and the synchronous belt 6 can be driven to rotate between the two rotating bodies, and the painting cloth and the synchronous belt 6 rotate synchronously, and the painting cloth absorbs the paint, and the paint is evenly applied to the wall. For example, Figure 1 In the position shown, hold the box body 1 so that the paint cloth on the outside of the first support rod 2 keeps in contact with the wall, and move the box body 1 upward. The paint cloth and the synchronous belt 6 rotate in a clockwise direction, and the paint can be evenly applied to the wall from bottom to top. In order to facilitate the painting operation by holding the box body 1, 1 to 2 operating handles 8 are provided on the outside of the box body 1.
