[0002] Currently, exterior wall waterproofing construction commonly employs methods such as brushing or roll material laying, with brushing being widely used due to its flexibility and adaptability. Traditional exterior wall waterproofing application often relies on manual hand-held brushes or rollers, which is not only labor-intensive and inefficient but also makes it difficult to ensure uniform coating, easily resulting in areas that are too thick or too thin, affecting the waterproofing effect. Furthermore, excess waterproofing coating can easily drip or run during construction, causing material waste and environmental pollution, which is difficult to clean up.

[0003] To improve construction efficiency, some auxiliary devices have emerged, but existing devices still have many shortcomings in practical applications: for example, the roller felt used for painting is mostly fixedly connected to the painting roller, and after long-term use, the felt needs to be replaced as a whole when it is worn or contaminated, which increases the cost of use; some devices lack an effective slurry recovery mechanism, and excess slurry cannot be reused, which is not in line with the concept of green construction; in addition, the scraping and cleaning function of existing devices is not perfect, making it difficult to clean excess slurry and debris on the roller felt in real time, which can easily lead to uneven painting or debris mixed into the coating, affecting the construction quality.

[0004] Therefore, this utility model proposes an auxiliary device for exterior wall waterproofing construction to solve the above problems.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Reference Figure 1-6 An auxiliary device for waterproofing construction of exterior walls includes a support shell 1, a brush roller 2, four strip plates 3, a handrail 31, a delivery pump 4, a connecting hose 42, and a loop pipe 41.

[0032] A support shaft 21 is fixedly installed on the coating roller 2. The support shaft 21 is rotatably installed in the support housing 1. A roller felt 22 is detachably installed on the outer periphery of the coating roller 2. In order to facilitate the replacement and fixing of the roller felt 22, it is not necessary to replace the entire coating roller 2, thus effectively reducing the cost of use. A continuous hook and loop fastener male layer is provided around the outer surface of the coating roller 2 in the circumferential direction. A hook and loop fastener female layer that can be completely adhered to the male layer is provided on the inner surface of the roller felt 22. The roller felt 22 is installed on the outer periphery of the coating roller 2 through the hook and loop fastener male layer and the hook and loop fastener female layer.

[0033] Four strip plates 3 are arranged parallel to each other and are rotatably installed on the front and rear sides of the support housing 1. The ends of the four strip plates 3 away from the support housing 1 are all hinged to the handrail 31, and the handrail 31 is fixedly installed with a handle 32 to facilitate the operator to control the support housing 1 to adjust the tilt angle. The delivery pump 4 is fixedly installed on the outside of the support housing 1. The connecting hose 42 is connected to the water inlet of the delivery pump 4. The loop pipe 41 is fixedly installed on the support housing 1 and connected to the water inlet of the delivery pump 4. The part of the loop pipe 41 located inside the support housing 1 is fixedly installed with a discharge nozzle 411 facing the brush roller 2.

[0034] A return pump 43 is fixedly installed on the bottom side of the support housing 1. The inlet of the return pump 43 is connected to the lowest point of the inner wall of the support housing 1. The outlet of the return pump 43 is connected to a return hose 431 that is connected to the connecting hose 42. This allows the waterproof slurry accumulated in the support housing 1 to be extracted and returned to the connecting hose 42, thereby achieving the effect of recycling and reuse. At the same time, it can also prevent excessive accumulation of waterproof slurry in the support housing 1.

[0035] Two parallel scraper strips 11 are fixedly installed on the inner side wall of the support housing 1 near the opening. Both scraper strips 11 are adapted to the roller felt 22 and can scrape off the excess paste adhering to the roller felt 22, thereby ensuring the uniformity of the coating. At the same time, they can also clean the roller felt 22 when it moves into the support housing 1, preventing the debris adhering to the roller felt 22 from entering the support housing 1.

[0036] In this embodiment, in order to avoid backflow of the waterproof slurry and to ensure normal delivery of the waterproof slurry, a one-way valve 44 is fixedly installed on both the connecting hose 42 and the return hose 431.

[0037] In this embodiment, in order to reduce the weight of the coating roller 2 and thus reduce the workload of the operator when using the device to carry out exterior wall waterproofing construction, the coating roller 2 is hollow.

[0038] In this embodiment, in order to provide effective support for the connecting hose 42 and facilitate the operator to better operate the device for the external wall waterproofing coating operation, the same connecting plate is fixedly installed on the two strip plates 3 on the right side. A support block 421 is fixedly installed on the connecting plate, the support block 421 is fixedly connected to the connecting hose 42, and two handles 33 are fixedly installed on the connecting plate.

[0039] In this embodiment, in order to facilitate operators to better understand the feeding and recycling of the waterproof slurry, and to facilitate quick assembly and disassembly with the external feeding hose, both the connecting hose 42 and the return hose 431 are made transparent, and a quick connector is provided at the end of the connecting hose 42 away from the delivery pump 4.

[0040] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0041] Working principle: When in use, first connect the power supply and connect it to the external feeding hose through the quick connector. Then, the operator holds the handle 32 on the support frame 31 and moves the device to the external wall construction area. Start the delivery pump 4. The waterproof slurry is delivered to the loop pipe 41 through the connecting hose 42 and sprayed evenly from the discharge nozzle 411 onto the roller felt 22 on the outside of the brush roller 2. At this time, the operator can adjust the angle and position of the support housing 1 by using the handle 33 in conjunction with the handle 32 to make the brush roller 2 in close contact with the wall surface and achieve uniform coating by pushing the device.

[0042] During the coating process, the two scrapers 11 clean the excess slurry on the surface of the roller felt 22 in real time to ensure uniform coating thickness and avoid debris residue. When the roller felt 22 rotates into the support housing 1, the scrapers 11 clean it further to prevent impurities from entering the support housing 1 and affecting the operation of the equipment.

[0043] As construction progresses, some unused slurry may accumulate at the bottom of the support shell 1. At this time, the return pump 43 is started to transport the accumulated slurry back to the connecting hose 42 through the return hose 431, so as to realize the recycling and reuse of the slurry. This process not only reduces material waste, but also effectively avoids overflow caused by excessive slurry in the support shell 1 and the increase in the workload of the operators.

[0044] The transparent connecting hose 42 and return hose 431 allow operators to observe the slurry flow at any time, ensuring smooth construction. The one-way valve 44 prevents slurry backflow, ensuring the stability and efficiency of slurry delivery. In addition, the hollow structure of the coating roller 2 reduces the overall weight, reduces operator fatigue during long-term operation, and thus improves work efficiency.

[0045] After construction is completed, operators can quickly remove the roller felt 22 through the male and female Velcro layers for cleaning or replacement.

[0046] The above provides a detailed description of an auxiliary device for exterior wall waterproofing construction provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
