Description

Technical Field

[0001] The invention relates to the technical field of paint storage containers, in particular to an environmentally friendly paint bucket which is convenient for paint recycling. Background Art

[0002] Environmentally friendly coatings refer to coating products whose performance and safety indicators meet the respective product standards and the technical requirements of national environmental labeling products. During the use of environmentally friendly coatings, they need to be stored in designated containers to facilitate their subsequent bringing to the construction site for construction;

[0003] During use, workers use paint brushes to paint walls and apply paint on the walls. When the paint brush is sticky with too much paint, paint will drip, resulting in a waste of paint. If the edge of the paint bucket is used to scrape off excess paint, a large amount of paint will stick to the surface of the paint bucket, and the paint may also drip over the paint bucket to the outside, making it difficult to clean. Moreover, most of the paint in the paint bucket cannot be used up in one time, and the brush is directly inserted into the bucket to dip in the paint. This will cause the paint in the bucket to be exposed to the air for a long time, which will cause the paint in the bucket to harden or the components to deteriorate, resulting in a waste of resources.

[0040] In this embodiment, a pull rod 26 is provided at the upper end of the top cover 3, and a plurality of bottom wheels 5 are provided at the lower end of the bottom tank 1, so that the structure can be easily moved as a whole, and the bottom wheels 5 can be universal wheels;

[0041] The environmentally friendly paint bucket presents a simple and practical industrial design style as a whole. From the appearance, it has a three-section structure of top, middle and bottom, which includes a top cover 3, a top tank 2 and a bottom tank 1 from top to bottom;

[0042] The top cover 3 is of a flat circular design, with a smooth and uniform upper surface, and a pull rod 26 is firmly mounted on the upper end. The pull rod 26 is made of a solid metal material, and the surface may be rust-proofed and have certain anti-slip textures, so that the user can apply force to pull the paint bucket;

[0043] The top tank 2 is cylindrical in shape, and the surface of the tank body is flat and smooth with good glossiness. The outer wall thereof is tightly mounted with a shell 16 and a second control box 15. The shell 16 wraps around a part of the top tank 2. The positioning seats 17 at both ends are slightly raised and seamlessly connected with the outer wall of the top tank 2. The overall lines are smooth and natural. The surface treatment of the positioning seat 17 is fine, and the edge of the opening 21 of the empty slot 19 is neat, which is used to accommodate a detachable filter cartridge 20. The second control box 15 is located in the middle part of the shell 16. Its outer shell is usually made of metal material, and the surface may be painted, which not only has protective performance, but also makes the overall appearance more consistent and professional. The second control box 15 is clearly marked with a second switch for controlling the second feed pump. The design of the switch is ergonomic and easy to operate.

[0044] The bottom tank 1 is also cylindrical and its diameter is adapted to the top tank 2. A plurality of bottom wheels 5 are evenly distributed at its lower end. The material of the bottom wheels 5 has good wear resistance and load-bearing capacity. The outer surface of the wheel may have a rubber texture, which can not only ensure stability during movement, but also effectively reduce wear on the ground and noise generation. A first control box 6 is installed on one side of the bottom tank 1. The appearance of the first control box 6 echoes the second control box 15, and a first switch for controlling the first feed pump is provided on its surface. There is no need to make too much description of the electrical equipment in the first control box 6 and the second control box 15. The interior is usually equipped with an independent power supply and a regulating device for switching circuits.

[0045] First, open the cover on the feeding pipe 4, add the environmentally friendly paint into the bottom tank 1 through the feeding pipe 4, and then close the cover;

[0046] When assembling the environmentally friendly paint bucket, align the block of the bottom tank 1 with the slot at the lower end of the top tank 2 to position the two initially, then firmly fix the top tank 2 to the upper end of the bottom tank 1 through the docking block 14 and bolts, and finally install the top cover 3 on the top of the top tank 2;

[0047] When using the paint, the top cover 3 is disassembled from the top tank 2, the first switch is turned on, the first feed pump in the first control box 6 is started, and the first valve 13 is opened at this time. The first feed pump extracts the paint from the bottom tank 1 through the first feed pipe 7, and delivers the paint to the three-way joint through the first discharge pipe 8, the transfer pipe 9 and the first delivery pipe 12. Then the paint can flow out through the injection pipe 23, and then be stored inside the top tank 2. When the paint reaches the specified liquid level in the top tank 2, the first switch is turned off. At this time, the first feed pump and the second valve 39 are both closed, and then tools such as brushes can be inserted into the top tank 2 to dip in the paint to meet the needs of brushing and other operations;

[0048] When the brush is dipped in paint, the handle of the brush is taken and the bottom end of the handle is inserted between the two extrusion shafts 36 at the trapezoidal groove. At this time, the brush is inserted into the paint in the top tank 2. Further shaking of the handle can make the brush dip in the paint evenly. At this time, the spring in the placement groove 42 will be squeezed by the positioning rod 32. As the handle is pulled, when the brush is between the two extrusion shafts 36, the two extrusion shafts 36 can be squeezed on the brush through the rebound effect of the spring. As the brush is pulled up, the excess paint on the brush can drip into the inside of the top tank 2, which is convenient for recycling the excess paint and will not drip into the outside, making the appearance of the paint bucket neater.

[0049] As the paint in the top tank 2 is consumed, the first switch can be temporarily turned on to continuously supply the top tank 2. This process will not expose all the paint in the bottom tank 1 to the air, making it difficult for the remaining paint in the bottom tank 1 to dry and harden or deteriorate, thereby avoiding waste of resources.

[0050] When the paint in the top tank 2 is used up, if there is still some paint left inside, the second switch is turned on at this time, the second feed pump can be started, and the second valve 39 can be opened. At this time, the paint will flow from the first guide groove 22 inside the top tank 2 through the second guide groove 41 and into the empty groove 19 from the bayonet. In this process, the paint will be filtered by the filter cartridge 20, and the filtered paint will be transported to the inside of the injection pipe 23 through the second feed pipe 40 through the second feed pipe 18, and then flow back to the inside of the top tank 2, so as to facilitate filtering the remaining paint in the top tank 2 and make the remaining paint in the top tank 2 convenient for subsequent use. Finally, the second switch is turned off and the top cover 3 is fixed on the top tank 2. Among them, the three-way joint design of the second feed pipe 18 at the bottom of the empty groove 19 and the feeding end of the second feed pump ensures the smoothness of the paint recovery path;

[0051] A first sealing ring is provided on the peripheral side of the opening 21, a baffle is provided on the upper end of the filter cartridge 20, a second sealing ring is provided on the lower end of the baffle, and an indicating arrow 38 is provided on the upper end of the positioning seat 17;

[0052] When the filter cartridge 20 needs to be replaced or cleaned, the filter cartridge 20 is taken out from the empty groove 19 of the positioning seat 17 by the toggle block 37. The operation is convenient. After the filter cartridge 20 is installed, the first sealing ring and the second sealing ring will be squeezed to ensure the sealing of the filter cartridge 20. By aligning the indicator arrow 38 with the toggle block 37, the opening 21 can be aligned with the second guide groove 41.

[0053] Two bases 31 are symmetrically arranged on the inner wall of the top tank 2. A driving screw 29 and a guide rod 30 that penetrate the protrusion 28 are arranged at the upper end of the base 31. The driving screw 29 is threadedly connected to the protrusion 28. The bottom end of the driving screw 29 is rotatably connected to the base 31. The protrusion 28 can be lifted and lowered along the guide rod 30. The positioning ring 33 is penetrated by the positioning rod 32, and the positioning ring 33 is slidably matched with the positioning rod 32. A locking rod 34 for limiting the positioning ring 33 is arranged on one side of the positioning rod 32. The locking rod 34 penetrates the positioning ring 33 and is threadedly matched with the positioning ring 33. One end of the locking rod 34 contacts the positioning rod 32.

[0054] When the extrusion shaft 36 is in use, if it is necessary to adjust the position of the extrusion shaft 36 in the top tank 2, the driving screw 29 can be rotated. Since the driving screw 29 is threadedly connected to the protrusion 28 and the bottom end is rotatably connected to the base 31, the protrusion 28 will rise and fall along the guide rod 30, so that the height of the extrusion shaft 36 can be adjusted. The springs in the grooves 42 at both ends of the cross plate 27, the positioning rod 32 and the positioning ring 33 on the support shaft 35 cooperate with each other to ensure the stability and reliability of the cross plate 27 during the adjustment process. The positioning ring 33 and the positioning rod 33 2 Sliding fit, the locking rod 34 can limit the positioning ring 33 to prevent it from accidentally moving. When it is necessary to adjust the spacing between the two extrusion shafts 36, the locking rod 34 is rotated through the action of the threaded structure to make one end of the locking rod 34 disengage from the positioning rod 32. At this time, the positioning ring 33 can slide on the positioning rod 32, and then the locking rod 34 can be locked, which is convenient for temporarily adjusting the spacing between the two extrusion shafts 36, and then convenient for adjusting the squeezing degree of the two extrusion shafts 36 on the brush, and convenient for dealing with brushes of different lengths, and has strong applicability.
