Description

Technical Field

[0001] The utility model relates to the technical field of wall painting, in particular to a wall painting device. Background Art

[0002] Wall painting is a common and important task during interior decoration. Traditional wall painting devices typically include a gripping rod and a brush roller. The operator uses the gripping rod to control the brush roller's movement across the wall to complete the painting operation. However, when painting high places such as ceilings, powder droplets often occur, which not only affects construction quality but can also cause ground contamination and material waste. To address this issue, installing a powder collector below the brush roller has become an effective solution. This design not only collects fallen powder, reducing waste and pollution, but also improves construction efficiency, allowing the operator to focus on the painting operation itself without the need for frequent floor cleaning.

[0003] Prior art wall painting devices typically utilize a fixed-size powder collector. While this design can address the problem of powder droplets to a certain extent, it lacks flexibility. Because the length of the brush roller can vary depending on construction requirements, a fixed-size collector often cannot fully cover brush rollers of varying lengths, resulting in poor collection efficiency. An overly long collector can cause inconvenience when working in confined spaces, while one that is too short cannot meet the needs of painting large areas. This design is difficult to adapt to diverse construction environments and requirements, limiting the practicality and applicability of wall painting devices. Utility Model Content

[0004] The main purpose of the utility model is to provide a wall painting device, aiming to solve the technical problem that the powder collector of the painting device in the prior art is fixed in length and cannot be adjusted to meet construction needs.

[0005] To achieve the above-mentioned purpose, the wall painting device proposed in the present invention includes a holding rod, a powder collector and a brush roller;

[0006] The powder collector includes a fixed collecting wall and a movable collecting wall, wherein the fixed collecting wall is fixedly connected to the holding rod, and the movable collecting wall is reciprocatingly disposed on the fixed collecting wall, and the fixed collecting wall and the movable collecting wall jointly define a powder collecting trough;

[0007] The brush roller is rotatably disposed in the powder collecting trough, and at least a portion of the peripheral wall of the brush roller extends from the notch of the powder collecting trough to paint the wall; wherein,

[0008] The movable collecting wall can move relative to the fixed collecting wall to extend or shorten the length of the powder collecting trough.

[0009] Optionally, the fixed collecting wall includes a fixed arc-shaped wall and a fixed end wall provided on one end of the fixed arc-shaped wall, the brush roller is rotatably provided on the fixed end wall, and a movable opening is formed at the other end of the fixed arc-shaped wall;

[0010] The movable collecting wall includes a movable arc-shaped wall, which matches the shape of the fixed arc-shaped wall and is slidably arranged on the fixed arc-shaped wall. The movable arc-shaped wall can slide along the extension direction of the fixed arc-shaped wall and extend or retract from the movable opening.

[0011] Optionally, a movable end wall is provided at the end of the movable arcuate wall away from the fixed end wall, the fixed end wall and the movable end wall are arranged opposite to each other, and the fixed end wall, the fixed arcuate wall, the movable arcuate wall and the movable end wall jointly define the powder collecting trough.

[0012] Optionally, the end of the brush roller away from the fixed end wall is rotatably provided on the movable end wall.

[0013] Optionally, a sliding groove is provided on the inner wall surface of the fixed arc-shaped wall, and the sliding groove and the fixed arc-shaped wall extend in the same direction;

[0017] The wall painting device of the technical solution of the present utility model cleverly solves the limitations of the fixed-size collectors in the prior art by establishing an adjustable structure between the fixed collection wall and the movable collection wall. The movable collection wall of the device can move relative to the fixed collection wall, thereby extending or shortening the length of the powder collection trough. This flexible design enables the collector to adapt to brush rollers of different lengths, effectively covering the entire working range of the brush roller. This not only improves the efficiency of powder collection, reduces material waste and environmental pollution, but also can adapt to various construction environments, whether it is painting large areas or working in small spaces. At the same time, the adjustable collection trough length allows the device to be shortened to the minimum size when not in use, which is convenient for storage and transportation.

[0027] The utility model provides a wall painting device.

[0028] In the embodiment of the present utility model, Figure 1 and Figure 2 As shown, the wall painting device includes a holding rod 1, a powder collector 2 and a brush roller 3;

[0029] The powder collector 2 includes a fixed collecting wall 21 and a movable collecting wall 22. The fixed collecting wall 21 is fixedly connected to the holding rod 1. The movable collecting wall 22 is reciprocally movable on the fixed collecting wall 21. The fixed collecting wall 21 and the movable collecting wall 22 jointly define a powder collecting trough 23.

[0030] The brush roller 3 is rotatably disposed in the powder collecting trough 23, and at least a portion of the peripheral wall of the brush roller 3 extends from the notch of the powder collecting trough 23 to paint the wall; wherein,

[0031] The movable collecting wall 22 can move relative to the fixed collecting wall 21 to extend or shorten the length of the powder collecting trough 23 .

[0032] Specifically, the holding rod 1 refers to the component used by the operator to hold and control the entire painting device, which is usually a long rod-shaped structure. The powder collector 2 is a device for collecting powder dropped during the painting process, and includes two main parts: a fixed collection wall 21 and a movable collection wall 22. The fixed collection wall 21 is a part fixedly connected to the holding rod 1, while the movable collection wall 22 can move relative to the fixed collection wall 21. The brush roller 3 is a rotatable cylindrical brush used to apply powder to the wall. The powder collection trough 23 is a space defined by the fixed collection wall 21 and the movable collection wall 22, and is used to collect dropped powder.

[0033] The fixed connection between the fixed collection wall 21 and the gripping rod 1 can be achieved in a variety of ways, such as bolting, welding, or integral molding. The reciprocating movement between the movable collection wall 22 and the fixed collection wall 21 can be achieved through a sliding connection. For example, a guide rail can be provided on the fixed collection wall 21, and a slider that matches the guide rail can be provided on the movable collection wall 22. The brush roller 3 can be mounted within the powder collection trough 23 via a bearing or other rotating mechanism, allowing it to rotate freely.

[0034] It is worth noting that the phrase "at least a portion of the peripheral wall of the brush roller 3 extends from the notch of the powder collecting trough 23" means that the brush roller 3 is not completely enclosed by the powder collecting trough 23, but rather partially protrudes from the trough so that it can contact the wall surface for painting. This design allows the brush roller 3 to function properly while allowing the powder collecting trough 23 to effectively collect fallen powder.

[0035] It can be understood that the wall painting device of the technical solution of the present invention cleverly solves the limitations of fixed-size collectors in the prior art by establishing an adjustable structure between the fixed collecting wall 21 and the movable collecting wall 22. The movable collecting wall 22 of the device can move relative to the fixed collecting wall 21, thereby extending or shortening the length of the powder collection trough 23. This flexible design enables the collector to adapt to brush rollers 3 of different lengths, effectively covering the entire working range of the brush roller 3. This not only improves the efficiency of powder collection, reduces material waste and environmental pollution, but also can adapt to various construction environments, whether it is painting large areas or working in small spaces. At the same time, the adjustable collection trough length allows the device to be shortened to the minimum size when not in use, which is convenient for storage and transportation. This innovative design greatly enhances the practicality and applicability of the wall painting device, and provides a more efficient, clean and flexible solution for interior decoration work.

[0036] Optionally, the fixed collecting wall 21 includes a fixed arc-shaped wall 211 and a fixed end wall 212 provided on one end of the fixed arc-shaped wall 211, the brush roller 3 is rotatably provided on the fixed end wall 212, and a movable opening is formed at the other end of the fixed arc-shaped wall 211;

[0037] The movable collecting wall 22 includes a movable arc wall 221, which matches the shape of the fixed arc wall 211 and is slidably arranged on the fixed arc wall 211. The movable arc wall 221 can slide along the extension direction of the fixed arc wall 211 and extend or retract from the movable opening.

[0038] Specifically, the fixed arcuate wall 211 and the movable arcuate wall 221 refer to wall structures with an arcuate cross-section. This arcuate design helps to better surround the brush roller 3 and guide the falling powder. The fixed end wall 212 is a closed structure provided at one end of the fixed arcuate wall 211, which is used to support one end of the brush roller 3. The movable opening refers to an open structure at the other end of the fixed arcuate wall 211, which allows the movable arcuate wall 221 to extend or retract therefrom. The movable arcuate wall 221 is the main component of the movable collecting wall 22, and can slide along the fixed arcuate wall 211, thereby changing the length of the powder collecting trough 23.

[0039] It is worth noting that the phrase “the movable arc wall 221 matches the shape of the fixed arc wall 211 ” means that the arc profiles of the movable arc wall 221 and the fixed arc wall 211 are similar or identical, which ensures that they can fit tightly when sliding to prevent powder leakage.

[0040] It can be understood that the arc design can better surround the brush roller 3 and improve the powder collection efficiency; secondly, the movable arc wall 221 can be extended or retracted from the movable opening, making the length adjustment of the powder collecting trough 23 more flexible; thirdly, the design of the fixed end wall 212 provides a stable support point for the brush roller 3, which is conducive to the stable operation of the brush roller 3.

[0041] Of course, the design of the present application is not limited thereto. In other embodiments, a flat plate-shaped structure may also be used to collect fallen powder.

[0042] Optionally, a movable end wall 222 is provided at the end of the movable arc wall 221 away from the fixed end wall 212, and the fixed end wall 212 and the movable end wall 222 are arranged opposite to each other. The fixed end wall 212, the fixed arc wall 211, the movable arc wall 221 and the movable end wall 222 jointly define the powder collecting trough 23.

[0043] By providing the movable end wall 222 , the powder collecting trough 23 can be kept closed at both ends at any length, thereby effectively preventing the powder from leaking from the end.

[0044] Optionally, the end of the brush roller 3 away from the fixed end wall 212 is rotatably provided on the movable end wall 222. By also providing a support point for the brush roller 3 on the movable end wall 222, the brush roller 3 can be supported at both ends at any length, thereby improving the rotation stability of the brush roller 3 and the uniformity of the brushing.

[0045] Optionally, a sliding groove 211a is provided on the inner wall surface of the fixed arc-shaped wall 211, and the sliding groove 211a and the fixed arc-shaped wall 211 extend in the same direction;

[0046] A sliding block is provided on the outer wall surface of the movable arc-shaped wall 221 , and the sliding block is slidably disposed in the sliding groove 211 a .

[0047] Specifically, the chute 211a is a long, grooved structure provided on the inner surface of the fixed curved wall 211, which guides the movement of the movable curved wall 221. The slider is a protruding structure provided on the outer surface of the movable curved wall 221, which matches the chute 211a and slides within it. This design of the chute 211a and slider forms a guiding mechanism, ensuring that the movable curved wall 221 can move smoothly and accurately along the fixed curved wall 211.

[0048] The connection between the chute 211a and the fixed curved wall 211 can be achieved in a variety of ways. For example, the chute 211a can be directly machined on the inner wall surface of the fixed curved wall 211 to form an integrated structure; or a separately manufactured chute 211a can be fixed to the fixed curved wall 211 by welding, gluing, or bolting. The connection between the slider and the movable curved wall 221 can also be achieved in a variety of ways, such as integral molding, welding, or removable bolt connection. The sliding of the slider in the chute 211a can be achieved by coating the slider surface with a low-friction material, or by using a lubricating material on the inner wall of the chute 211a to reduce friction.

[0049] It is not difficult to understand that the design of the chute 211a and the slider provides a stable guiding mechanism, ensuring that the movement of the movable arc wall 221 is smoother and more precise, which helps to maintain the sealing of the powder collecting trough 23; secondly, this design makes the adjustment of the movable arc wall 221 easier and more controllable, and the operator can easily adjust the length of the powder collecting trough 23; thirdly, the structure of the chute 211a and the slider enhances the stability of the entire device and reduces the shaking and wear of the movable parts.

[0050] In addition, by setting the chute 211a on the inner wall surface of the fixed curved wall 211, when the powder in the powder collecting trough 23 is cleaned with water, the chute 211a is directly exposed to the cleaning water. The operator can directly clean the chute 211a while cleaning the inner wall of the fixed curved wall 211, without the need for additional cleaning steps. This greatly simplifies the cleaning process and saves time and labor. Secondly, because the chute 211a is located on the inner wall, water can naturally flow through the chute 211a, washing away the accumulated powder and dirt, ensuring that the chute 211a always remains clean and maintaining the smooth operation of the sliding mechanism. Thirdly, this design eliminates the need to clean the outer wall surface because all parts that need to be cleaned are concentrated inside, making the cleaning process more efficient and thorough.

[0051] Optionally, a gap is left between the end of the sliding groove 211a away from the fixed end wall 212 and the periphery of the movable opening to prevent the slider from falling out of the periphery of the movable opening during the sliding process.

[0052] The gap can be set in a variety of ways. For example, when designing the fixed curved wall 211, the length of the slide groove 211a can be designed to be slightly shorter than the fixed curved wall 211, so that a gap is naturally formed between the end of the slide groove 211a and the periphery of the movable opening. Alternatively, a block or limiting structure can be provided at the end of the slide groove 211a to prevent the slider from moving further toward the movable opening.

[0053] The technical effects of this design are mainly reflected in the following aspects: First, by setting the gap, the slider is effectively prevented from escaping from the movable opening, thereby improving the safety and reliability of the device; second, this design allows the movable arc wall 221 to extend to the maximum extent, thereby achieving maximum adjustment of the length of the powder collecting trough 23 without affecting the stability of the structure.

[0054] Optionally, the material of the fixed arc-shaped wall 211 and the material of the movable arc-shaped wall 221 are both transparent materials.

[0055] Specifically, the transparent material can be various transparent plastics, such as polycarbonate, acrylic, etc., or tempered glass or other transparent composite materials. The fixed arc wall 211 and the movable arc wall 221 are both made of transparent materials, which means that the entire shell of the powder collecting trough 23 is visible.

[0056] The technical effects of this design are mainly reflected in the following aspects: First, the transparent material enables the operator to intuitively observe the situation inside the powder collection trough 23, including the degree of powder collection and distribution, etc., which helps to promptly determine whether cleaning is needed; secondly, during the painting process, the operator can monitor the working status of the brush roller 3 in real time, such as whether the material is evenly stained, whether there is blockage, etc., which is conducive to timely adjustment of the operation mode; thirdly, the transparent design also makes it easy to check whether the inside of the device is completely clean, thereby improving cleaning efficiency and quality.

[0057] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
