[0036] In order to make the purpose, technical solutions and advantages of this application clearer, the following Figure 1-3 This application is further described in detail. Obviously, the embodiments described are only a part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] It should be understood that although the terms first, second, third, etc. may be used to describe in the embodiments of the present application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, without departing from the scope of the embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0038] The present application provides a portable paint brushing device, comprising: a box body 1; an oil pump 2 is provided at the inner bottom of the box body 1; the discharge end of the oil pump 2 passes through the box body 1 and is connected to a painting structure 4 through an oil outlet pipe 3; the painting structure 4 comprises: a supporting oil shell 41 connected to the oil outlet pipe 3; the supporting oil shell 41 is connected to a roller 43 through a telescopic structure 42; a plurality of oil spray holes 44 are provided at intervals at the front end of the supporting oil shell 41 corresponding to the position of the roller 43; an opening and closing structure for opening and closing the oil spray holes 44 is provided on the telescopic structure 42.

[0039] It can be understood that the interior of the box 1 is a hollow structure for storing the painting liquid; universal wheels are also provided at the bottom of the box 1; a pressure relief valve is also provided on one side of the box 1; the pressure relief valve is used to prevent excessive pressure inside the box 1; and a painting liquid anti-sway plate is provided in the middle part of the interior of the box 1.

[0040] It can be understood that the present application facilitates the brushing operation by improving the design of the brushing structure 4; during use, when the roller 43 contacts the brushing surface, a certain force is applied to the roller 43, so that the roller 43 pushes the telescopic structure 42 to move toward the inside of the supporting oil shell 41, thereby driving the opening and closing structure 45 to open the oil spray hole 44, releasing the paint inside the supporting oil shell 41, and realizing the brushing operation by rolling the roller 43; the advantage of this design compared to the existing technology is that the user can control the opening and closing of the oil spray hole 44 according to the size of the force applied to the roller 43, thereby facilitating the brushing operation.

[0041] Optionally, the telescopic structure 42 includes: a support rod 420 rotatably connected to both sides of the roller 43; one end of the support rod 420 extends to the inside of the supporting oil shell 41 and is slidably connected to the guide cylinder 421; a reset spring 422 is arranged between the support rod 420 and the guide cylinder 421; wherein a central axis is arranged between the two support rods 420, and the roller 43 is rotatably connected between the two support rods 420 through the central axis.

[0042] When painting, the roller 43 acts on the support rods 420 on both sides to push the opening and closing structure 45, thereby opening the oil injection hole 44; when painting is not needed, just separate the roller 43 from the painting surface, and the support rod 420 returns to its position under the action of the return spring 422, thereby driving the opening and closing structure 45 to close the oil injection hole 44, avoiding the outflow of paint inside the oil injection hole 44 and saving material costs.

[0043] Optionally, a sealing structure is provided on the outside of the portion where the support rod 420 extends into the guide cylinder 421; the sealing structure includes: a sealing groove provided on the outside of the support rod 420 and a sealing ring provided in the sealing groove; through the design of the sealing structure, the paint inside the support oil shell 41 is prevented from entering the inside of the guide cylinder 421, causing the support rod 420 to get stuck during movement.

[0044] Optionally, oil baffles 46 are provided on both sides of the supporting oil shell 41; wherein, the roller 43 is located between the two oil baffles 46; the design of the oil baffles 46 can prevent paint from splashing on the roller 43 during the painting process, thereby affecting the painting quality.

[0045] Optionally, the opening and closing structure 45 includes: a push plate 450 fixedly arranged between two support rods 420; wherein, the push plate 450 is located inside the supporting oil shell 41, and an oil sealing plug 451 for opening and closing the oil injection hole 44 is provided on one side of the push plate 450 corresponding to the position of the oil injection hole 44.

[0046] It can be understood that when in use, the two support rods 420 synchronously drive the push plate 450 to move, thereby opening the oil injection hole 44. When out of use, under the action of the return spring 422, the oil plug 451 closes the oil injection hole 44.

[0047] Compared with the existing design, the advantage is that the structural design of the push plate 450 and the support rod 420 can not only realize the opening and closing function of the oil injection hole 44, but also ensure the stability of the support rod 420 during the movement to avoid jamming.

[0048] Optionally, the structure of the oil sealing plug 451 is compatible with the structure of the oil injection hole 44, and both are conical structures; it can be understood that the advantage of adopting a conical structure design is to ensure the sealing effect between the oil sealing plug 451 and the oil injection hole 44 to prevent paint leakage. Secondly, the user can adjust the opening and closing degree of the oil injection hole 44 by controlling the magnitude of the force applied by the roller 43, thereby adjusting the oil output of the paint, thereby improving the painting effect while saving material costs.

[0049] Optionally, the oil outlet pipe 3 is connected to the outside of the box body 1 through a limiting structure 5; the limiting structure 5 includes: two sets of parallel limiting plates 51 and limiting blocks 52 cooperating with the limiting plates 51; wherein, a receiving groove for the oil outlet pipe 3 to pass through is formed between the two limiting plates 51;

[0050] One side of each of the limit plates 51 is fixed on the box body 1, and the upper part of the limit plate 51 is provided with a limit slot 53 that cooperates with the limit block 52; the limit block 52 is fixedly arranged on one side of the oil outlet pipe 3; the limit block 52 includes: a rod 520 that is engaged with the inside of the limit slot 53 and a cap 521 arranged at the free end of the rod 520; it can be understood that the design of the cap 521 prevents the limit block 52 from detaching from the limit slot 53.

[0051] When in use, it is only necessary to align the limiting blocks 52 on both sides of the oil outlet pipe 3 with the limiting slots 53 and place the oil outlet pipe 3 . The operation is simple and the stability is good.

[0052] Optionally, the oil outlet pipe 3 includes: a retractable hose and a hard pipe connected to the hose; wherein the limit block 52 is arranged on one side of the hard pipe, and the discharge port of the hard pipe is connected to the supporting oil shell 41; the lower end of the hose is connected to the oil pump 2; it can be understood that the user can adapt and select the length of the hose according to actual needs.

[0053] Optionally, a feeding pipe 6 is further provided on the top of the box body 1; the top of the feeding pipe 6 is rotatably connected to a closing cover plate 7 for closing the outlet of the feeding pipe 6; wherein the closing cover plate 7 is rotatably connected to the feeding pipe 6 via a support shaft.

[0054] It can be understood that compared with the existing technology, this application saves material costs, is simple to operate, and is highly practical.
