[0025] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0026] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0027] In the description of this utility model, "a plurality" means more than two. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] In light of the background art, it is known that paint storage requires airtightness when not in use. Conventional storage cans cannot effectively isolate unused paint from air after opening. Therefore, the present invention proposes a paint vacuum storage can that effectively isolates unused paint from air, thereby extending the shelf life of the paint.

[0030] Please also refer to Figure 1 、 Figure 2 and Figure 4 The paint vacuum storage tank provided by the embodiment of the present invention includes a tank body 1, a support frame 101 is fixedly connected to the top of the tank body 1, a discharge pipe 102 is provided at the bottom of the tank body 1, the discharge pipe 102 is connected to the interior of the tank body 1, and a sealing cover 103 is provided on the top of the tank body 1, wherein;

[0031] A pressure control assembly 2 is provided inside the cover 103. The pressure control assembly 2 includes a rotating drum 201 threadedly connected to the cover 103. The rotating drum 201 has a cavity with an open top, and a plurality of air holes 202 communicating with the cavity are provided on the bottom side wall of the rotating drum 201. A sealing ring 203 is fixedly connected to the bottom of the rotating drum 201. A protrusion surrounding the rotating drum 201 is provided at the bottom of the cover 103, and the bottom of the protrusion is formed with a concave closing surface that closes with the sealing ring 203.

[0032] According to the paint vacuum storage tank of the embodiment of the present invention, the tank body 1 is sealed by the cover 103, and the paint stored in the tank body 1 is taken out by the discharge pipe 102. At the same time, the pressure control component 2 provided on the cover 103 can adjust the vacuum degree in the tank body 1 by rotating the drum 201. Specifically, the rotating drum 201 is rotated so that the sealing ring 203 at its bottom is separated from the concave closing surface, and the outside air can enter the tank body 1 from the air vent 202 through the cavity of the drum 201. At this time, the interior of the entire tank body 1 is in a state of communication with the outside world. On this basis, the paint in the tank body 1 can be taken out through the discharge pipe 102; or the air in the tank body 1 can be extracted by connecting a vacuum machine to the drum 201, so that the paint in the tank body 1 is in a vacuum storage state and the storage period is increased. Obviously, after evacuation, the drum 201 can be rotated again to close the sealing ring 203 and the concave closing surface, thereby cutting off the connection between the vent hole 202 and the interior of the tank body 1, thereby fully maintaining the vacuum state within the entire paint vacuum storage tank. In this way, a storage method can be provided that facilitates immediate access to paint and effectively extends the shelf life of the paint.

[0033] It is understandable that the discharge pipe 102 may be provided with a discharge valve, or be connected to a discharge valve, so that the paint can be easily taken out through the discharge valve when needed, or the vacuum state of the paint vacuum storage tank can be effectively guaranteed when storing the paint.

[0034] Please also refer to Figure 1 and Figure 2 In some embodiments of the present invention, a protective shell 301 is provided at the bottom of the tank body 1, and a motor 302 is provided inside the protective shell 301. The output end of the motor 302 is fixedly connected to a scraper 303 through a transmission shaft, and the scraper 303 acts on the stirring area between the protective shell 301 and the bottom side wall of the tank body 1.

[0035] Obviously, the stirring area here is the rotation space where the scraper 303 is located. The scraper 303 can fully stir the paint during the rotation process and improve the discharge efficiency of the paint.

[0036] Please see further Figure 2 In some embodiments of the present invention, an inclined extrusion slope is provided at the end of the scraper 303, which is close to the bottom side wall of the tank body 1 and has a preset angle, and the inlet of the discharge pipe 102 is in the area corresponding to the angle.

[0037] It is understood that the bottom wall and sidewall of the tank body 1 are also inclined surfaces with a slope. When the scraper 303 rotates, the arrangement of the extrusion slope can create a certain extrusion effect between the paint and the bottom wall of the tank body 1. In this way, when the scraper 303 rotates to approach the inlet of the discharge pipe 102, the paint can be squeezed into the discharge pipe 102, thereby fully improving the discharge effect of the paint.

[0038] In a further embodiment of the present invention, a portion of the edge of the inlet of the discharge pipe 102 is sunken to form a coordinated slope adapted to the extrusion slope. The coordinated slope and the extrusion slope can be parallel to each other or at a certain angle to improve the discharge efficiency of the coating.

[0039] Please refer again Figure 2 In some embodiments of the present invention, a mounting assembly 4 is provided between the cover 103 and the tank body 1, and the cover 103 is detachably connected to the tank body 1 via the mounting assembly 4. Obviously, the mounting assembly 4 is used to meet the requirements of quick release and locking between the cover 103 and the tank body 1. Its design forms vary, and the present invention provides a built-in reset locking form.

[0040] Specifically, if Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5As shown, the installation and disassembly component 4 includes a plurality of plug blocks 401 fixedly connected to the edge of the cover 103, and a placement groove is provided inside each plug block 401. A slidable limit block 402 and a retractable spring 403 are provided in the placement groove. One end of the spring 403 is connected to or supports the limit block 402, and the other end of the spring 403 is connected to or supports the placement groove; the limit block 402 can compress the spring 403 under the action of external force and retract into the placement groove, so that the cover 103 can be quickly separated from the tank body 1; or the limit block 402 extends from the placement groove under the resetting action of the spring 403 and clamps the tank body 1 to achieve a locking connection between the cover 103 and the tank body 1.

[0041] Please see further Figure 3 In a further embodiment of the present invention, a fixing ring 408 and a push ring 104 that is located below the fixing ring 408 and can move are provided on the top of the tank body 1. The outer surface of the tank body 1 is provided with a plurality of slide grooves 406 opened along the axial direction of the tank body 1. The push ring 104 is movably connected to the slide groove 406 through the connecting block 405; the limit block 402 can be retracted into the placement groove under the action of the push ring 104, or be clamped between the push ring 104 and the fixing ring 408 under the reset action of the spring 403.

[0042] Please refer again Figure 3 In a further embodiment of the present invention, a push block 404 is fixedly connected to the push ring 104 corresponding to the limit block 402. The push block 404 can move with the push ring 104 to act on the limit block 402. Specifically, when the push block 404 moves upward with the push ring 104, it can push the limit block 402 to move the compressed spring 403 and retract it into the placement groove. At this time, the cover 103 can be lifted upward and quickly separated from the can body 1. When the push block 404 moves downward with the push ring 104 to return to its original position, a locking space is formed between the push block 404 and the fixed ring 408. The limit block 402 is forced into this locking space under the return action of the spring 403, and the cover 103 can be quickly locked with the can body 1.

[0043] Obviously, when the cover 103 needs to be removed, the lock can be quickly released by lifting the push ring 104; and by releasing the push ring 104 to put it in an unlifted state, the cover 103 can be pressed down on the tank body 1 to achieve a quick locking between the two. The whole operation process is convenient and practical.

[0044] Optionally, a wedge-shaped surface for guiding is provided at the end of the limiting block 402 so as to facilitate rapid interaction between the limiting block 402 and the pushing block 404 .

[0045] Optionally, the top end of the push block 404 is provided with an adaptive curvature corresponding to the wedge surface to improve the efficiency of the action.

[0046] Please refer to Figure 4 and Figure 5 In a further embodiment of the present invention, the inner wall of the retaining ring 408 is provided with a square groove 410 adapted to fit the push block 404, and a plurality of spring clips 409 are fixedly connected to the top of the retaining ring 408. When the cover 103 is closed and locked with the can body 1, the spring clips 409 are able to elastically deform under pressure. When the cover 103 and the can body 1 are released, the spring clips 409 return to their original position and provide a reset function, allowing the cover 103 to quickly escape upward, thereby further improving the separation efficiency of the cover 103.

[0047] Please refer again Figure 4 and Figure 5 In some embodiments of the present invention, a ring groove is provided on the top of the tank body 1, and a rubber ring 407 is provided on the sealing cover 103 corresponding to the ring groove.

[0048] Obviously, the rubber ring 407 here is used to close the annular groove when the cover 103 closes the tank body 1, thereby improving the vacuum effect of the entire paint vacuum storage tank.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
