Description

Technical Field

[0001] This application belongs to the field of coating application technology, and specifically relates to a coating application bucket. Background Technology

[0002] The coating bucket is a container used to hold the coating during nano-coating application. During application, workers dip their brushes into the bucket to pick up the coating. Because nano-coatings require an extremely thin application layer, using too much coating will result in an excessively thick film, causing rainbow-like patterns. Therefore, after picking up the coating, the brush must be manually wrung out before evenly applying the coating to the area to be treated.

[0003] Currently used coating containers are mostly square or round, with their bottoms in direct contact with the ground or metal roof. Ground temperatures can reach 60℃~70℃, and metal roof temperatures can reach 50℃~60℃. Since nano-coatings are mostly alcohol- or resin-based, the coating in the container is prone to accelerated evaporation or curing due to heat, resulting in waste. Furthermore, manually wringing out the coating leads to inconsistent material control, resulting in low application efficiency and inconsistent application thickness, further contributing to coating waste. Utility Model Content

[0004] The purpose of this application is to provide a paint dipping bucket that aims to reduce paint waste by reducing external heat transfer and achieving uniform and controllable dipping.

[0005] To achieve the above objectives, this application provides a paint dipping bucket, the paint dipping bucket comprising: Lower housing; The upper housing is detachably installed on the lower housing and together with the lower housing to form a hollow cavity. The side of the upper housing away from the lower housing forms a material tank for receiving paint. A scraper is used to scrape off excess paint from the paint brush, and the scraper is located on the upper housing.

[0006] In some embodiments, the circumferential sidewalls of the trough are inclined, and the opening size of the trough is larger than the bottom size of the trough.

[0007] In some embodiments, both the longitudinal and cross sections of the trough are inverted trapezoids.

[0008] In some embodiments, the scraper is detachably connected to the upper housing.

[0009] In some embodiments, the upper housing is provided with two corresponding inner sides and locking seats, and the two ends of the scraper are respectively locked and fixed to the two locking seats.

[0010] In some embodiments, the scraper bar is integrally formed with the upper housing.

[0011] In some embodiments, the scraper bar is provided with a scraping section.

[0012] In some embodiments, the periphery of the upper housing has a downwardly extending first sidewall, and the periphery of the lower housing has an upwardly extending second sidewall, wherein the first sidewall and the second sidewall are detachably connected.

[0013] In some embodiments, one of the first sidewall and the second sidewall is provided with a slot, and the other is provided with a buckle that engages with the slot.

[0014] In some embodiments, a heat insulation pad is also provided at the connection between the upper housing and the lower housing.

[0015] This utility model's technical solution includes a structure in which a lower shell and a detachable upper shell enclose a hollow cavity, and a scraper is installed on the upper shell. Due to the heat-insulating design of the hollow cavity and the use of a scraper to remove excess paint, it effectively solves the technical problems in existing technologies where the paint evaporates and hardens due to direct contact between the paint bucket and the ground, as well as the low efficiency and uneven material control caused by manual wringing. This results in reduced material waste, ensured uniform construction thickness, and improved construction efficiency.

[0016] Other features and advantages of the embodiments of this application will be described in detail in the following detailed description section. Attached Figure Description

[0018] Explanation of reference numerals in the attached figures Detailed Implementation

[0019] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] This utility model proposes a paint application bucket 100, which is used in conjunction with a paint brush to achieve the application of nano-coatings. The paint brush has the structure of a flat mop to increase the contact area between the paint brush and the application area, thereby improving the application efficiency.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figures 1 to 6 As shown in the embodiment of this utility model, the paint application bucket 100 includes a lower shell 10, an upper shell 20, and a scraper 30. The upper shell 20 is detachably installed on the lower shell 10 and forms a hollow cavity 40 with the lower shell 10. A material trough 50 for receiving paint is formed on the side of the upper shell 20 away from the lower shell 10. The scraper 30 is used to scrape off excess paint from the paint brush and is located on the upper shell 20.

[0023] The upper shell 20 and lower shell 10 can be made of metal or plastic, with a wall thickness of at least 2 mm. A hollow structure is formed between the upper shell 20 and lower shell 10 to achieve thermal insulation, effectively preventing heat from the ground or metal roof from being transferred from the lower shell 10 to the upper shell 20, thus avoiding heating of the nano-coating in the material tank 50. Specifically, the hollow chamber 40 is a closed chamber with a height of at least 40 mm. The closed chamber effectively suppresses airflow. Furthermore, the air inside the hollow chamber 40 is a poor conductor of heat, effectively preventing the nano-coating from indirectly contacting the ground or metal roof through the shell. Although the air layer can also conduct heat, its conductivity is much lower than that of metal or plastic, significantly reducing the heat transferred to the upper shell 20 through the air layer.

[0024] The separate design of the upper shell 20 and the lower shell 10 has at least the following advantages: firstly, it facilitates molding and reduces processing difficulty; secondly, it allows for assembly or disassembly for use according to actual needs. It is understood that assembling the upper shell 20 and the lower shell 10 is to form a hollow cavity 40 for heat insulation. When the construction environment is not hot, the upper shell 20 and the lower shell 10 can be disassembled to obtain two containers. This detachable connection broadens the application range of the paint dispensing bucket 100. Furthermore, at least one of the upper shell 20 and the lower shell 10 is equipped with a handle (not shown in the figure). In addition, the bottom of the lower shell 10 is equipped with pulleys (not shown in the figure). The purpose of the handle and pulleys is to facilitate the movement or handling of the paint dispensing bucket 100. Furthermore, the pulleys can also create a gap between the bottom of the lower shell 10 and the ground or metal roof, further improving the heat insulation effect.

[0025] The scraper 30 is used to scrape off excess paint from the paint brush, solving the problems of inconsistent drying and low efficiency associated with manually wringing out the paint brush. The scraper 30 can be cylindrical or prismatic; in one embodiment of this invention, it is a cylindrical rod with a diameter greater than 10mm. The scraper 30 is horizontally positioned within the paint trough 50, near its opening. It can be fixed or detachably connected. When the flat paint brush is dipped into the paint trough 50 and removed, the worker can bring the flat surface of the brush into contact with the scraper 30 and move the brush back and forth. After scraping, excess paint drips down and returns to the paint trough 50.

[0026] like Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown in the embodiment of this utility model, the circumferential sidewall of the material trough 50 is inclined, and the opening size of the material trough 50 is larger than the bottom size of the material trough 50. Designing the material trough 50 to be wider at the top and narrower at the bottom can effectively prevent construction workers from pouring too much material and causing waste. The bottom size of the material trough 50 is adapted to the size of the paint brush, that is, the paint brush can be completely immersed in the bottom of the material trough 50 to ensure that the entire paint brush is covered with nano paint.

[0027] like Figure 4 and Figure 5As shown, in some embodiments, the longitudinal section and cross section of the trough 50 are both inverted trapezoidal. The upper shell 20 includes a first bottom plate 21, a first side plate 22, a second side plate 23, a third side plate 24, and a fourth side plate 25. The first bottom plate 21 is rectangular and has a long side and a short side. The first side plate 22 and the third side plate 24 are respectively connected to the two short sides of the first bottom plate 21. The second side plate 23 and the fourth side plate 25 are respectively connected to the two long sides of the first bottom plate 21. The sides of adjacent side plates are also connected, thereby forming a trough 50 in the shape of an inverted truncated pyramid with both its longitudinal section and cross section being inverted trapezoidal.

[0028] The first base plate 21 has a length of at least 380 mm and a width of at least 60 mm to accommodate the size of commonly used paintbrushes. The second side plate 23 and the fourth side plate 25 have the same inclination angle. The two ends of the scraper 30 are fixed to the second side plate 23 and the fourth side plate 25, respectively. The angle between the first side plate 22 and the first base plate 21 is defined as θ1, and the angle between the second side plate 23 and the first base plate 21 is defined as θ2, where θ1 < θ2. The scraper 30 is located close to the first side plate 22. Setting the inclination angle of the first side plate 22 to be gentler can play a guiding role, that is, after scraping, the excess paint in the paintbrush can flow back into the material trough 50 along the first side plate 22.

[0029] In one embodiment of this utility model, the scraper rod 30 is detachably connected to the upper housing 20, and the second side plate 23 and the fourth side plate 25 are respectively provided with structures for detachable connection with the scraper rod 30. Taking a snap-fit ​​connection as an example, such as... Figure 2 , Figure 4 and Figure 6 As shown, the upper housing 20 has two corresponding snap-fit ​​seats 231 on its two inner sides, namely, the second side plate 23 and the fourth side plate 25 are each provided with snap-fit ​​seats 231. The two ends of the scraper rod 30 are respectively snapped and fixed to the two snap-fit ​​seats 231. The scraper rod 30 is a cylindrical rod, and the snap-fit ​​seats 231 have a communicating guide groove and a locking slot. The end of the scraper rod 30 slides into the guide groove and is locked in place by the locking slot. Those skilled in the art will understand that this application is not limited to the above-mentioned snap-fit ​​connection; it can also be a threaded connection, a magnetic connection, etc. Other structural forms that can achieve detachable connections should also fall within the protection scope of this application.

[0030] The scraper 30 is detachable, which makes it easy to replace or clean the scraper 30. Removing the scraper 30 also makes it easy to clean the material tank 50.

[0031] In another embodiment of this utility model, the scraper 30 and the upper housing 20 are integrally formed. Taking plastic material as an example, the scraper 30 and the upper housing 20 are integrally injection molded. The integral molding design can improve the stability of the structure and reduce costs.

[0032] The scraper bar 30 is provided with a scraping part 31 for auxiliary scraping. The scraping part 31 can be in various forms, such as block, sheet or hole.

[0033] like Figure 5 As shown, in one embodiment of this utility model, the scraper part 31 is block-shaped, and scraper strips are protruding from the outer wall surface of the scraper rod 30. There are multiple scraper strips that extend along the length direction of the scraper rod 30, and the multiple scraper strips are evenly distributed. The cross-section of the scraper strips can be semi-circular, rectangular, or trapezoidal to effectively scrape off excess paint from the paint brush and reduce damage to the paint brush.

[0034] In another embodiment of this utility model, the scraping part 31 is sheet-shaped (not shown in the figure), and the outer wall surface of the scraping rod 30 is provided with scraping blades. The scraping blades are thinner than the scraping strips. Multiple scraping blades are arranged in a uniform manner to provide a larger contact area and thus achieve a better scraping effect.

[0035] In another embodiment of this utility model, the scraping part 31 is hole-shaped (not shown in the figure). Specifically, the scraping part 31 is a scraping hole that penetrates the scraping rod 30. The scraping hole can be a circular, elliptical, square or elongated through hole. Multiple scraping holes are arranged in an array along the length direction of the scraping rod 30. When the flat surface of the paint brush is squeezed and scraped by the scraping rod 30, the excess paint will be scraped off through the scraping hole and flow back into the material tank 50 below.

[0036] Those skilled in the art will understand that the block, sheet, and perforated scraping parts 31 can be used individually or in combination without conflict. Furthermore, the scraping parts 31 of this application are not limited to the block, sheet, or perforated shapes mentioned above, and other structural forms that can achieve scraping should also be within the scope of protection of this application.

[0037] like Figure 4 and Figure 5 As shown, the upper housing 20 has a downwardly extending first sidewall 26 around its periphery, and the lower housing 10 includes a second base plate 11. The second base plate 11 has an upwardly extending second sidewall 12 around its periphery. The second base plate 11 is rectangular, and the four second sidewalls 12 are perpendicular to the second base plate 11 and surround it. The first sidewall 26 and the second sidewall 12 are detachably connected. The first sidewall 26 and the second sidewall 12 can be connected by a sleeve, a snap-fit ​​connection, or a threaded fastener connection.

[0038] Taking the socket connection as an example, the first sidewall 26 is fitted onto the outer periphery of the second sidewall 12, meaning the outer wall surface of the second sidewall 12 and the inner wall surface of the first sidewall 26 are in contact with each other. Alternatively, the first sidewall 26 can be inserted into the inner side of the second sidewall 12, meaning the outer wall surface of the first sidewall 26 and the inner wall surface of the second sidewall 12 are in contact with each other. The socket connection method offers the advantages of convenient assembly and disassembly, as well as a simple structure; assembly can be achieved simply by utilizing the interference fit of the materials themselves.

[0039] like Figure 2 , Figure 4 and Figure 5 As shown, taking a snap-fit ​​connection as an example, one of the first sidewall 26 and the second sidewall 12 has a slot, and the other has a snap-fit ​​that mates with the slot. That is, the first sidewall 26 can have multiple slots along its circumference, and the second sidewall 12 can have multiple corresponding snap-fits; or the first sidewall 26 can have multiple snap-fits along its circumference, and the second sidewall 12 can have multiple corresponding slots. The snap-fits and slots correspond one-to-one and are snap-fit ​​connected respectively.

[0040] The threaded fastener connection, that is, the first sidewall 26 and the second sidewall 12 are connected by screws or bolts, will not be described in detail here.

[0041] To achieve better heat insulation, a heat insulation pad (not shown in the figure) is also provided at the connection between the upper shell 20 and the lower shell 10. Since the upper shell 20 and the lower shell 10 are designed separately, heat from the ground or metal roof can easily be transferred to the material tank 50 through the connection point between these two shells, affecting the overall heat insulation effect. Therefore, the heat insulation pad can further reduce heat transfer. The heat insulation pad can be made of rubber, silicone, or other materials with heat insulation properties. The heat insulation pad is arranged along the circumference of the hollow cavity 40, meaning that a heat insulation pad is provided at the connection point between the upper shell 20 and the lower shell 10. This heat insulation pad can effectively block heat from being conducted to the nano-coating in the material tank 50 through the connection point.
